What is the rate of return when 30 shares of Stock
A, purchased for $15/share, are sold for $480? The
commission on the sale is $6.
Rate of Return = [?] %
Give your answer as a percent rounded to the
nearest tenth
Answer:
5.1%
Step-by-step explanation:
We are told that 30 shares of Stock are purchased for $15/share..
This gives a total value of: 30 × 15 = $450.
Now,they are sold for $480 with a commission of $6. This means the final money getting to the seller is; 480 - 6 = $474.
Thus; rate of return percentage = (474 - 450)/474) × 100% = 5.06%
To the nearest tenth gives; 5.1%
The rate of return is 5.1%.
Given that,
A, purchased for $15/share, are sold for $480.The commission on the sale is $6.Based on the above information, the calculation is as follows:
The total value should be
[tex]= 30 \times 15[/tex]
= $450.
Since it is sold for $480 along with commission of $6 so final money should be
= 480 - 6
= $474.
Now rate of return is
[tex]= ((474 - 450)\div 474) \times 100%[/tex]
= 5.06%
= 5.1%

John works two jobs. He earns $10 an hour babysitting his neighbor's children and $15 an hour mowing lawns in his neighborhood. Last week he worked a total of 20 hours and earned a total of $240.
Drag and drop numbers in the boxes to create an equation which models this situation if x = the number of hours he spent babysitting and y = the number of hours he spent mowing lawns last week.
The number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.
What is an equation?An equation is a mathematical statement that is made up of two expressions connected by an equal sign.
Given that, John works two jobs. He earns $10 an hour babysitting his neighbour's children and $15 an hour mowing lawns in his neighbourhood. Last week he worked a total of 20 hours and earned a total of $240.
Let the x be the number of hours he spent babysitting and y be the number of hours he spent mowing lawns last week,
Establishing the equation, we get,
x+y = 20
x = 20-y......(i)
10x+15y = 240.......(ii)
Using the equation (i) in (ii), we get
10(20-y)+15y = 240
200-10y+15y = 240
5y = 40
y = 8
Put y = 8 in eq(i)
x = 20-8
x = 12
Hence, the number of hours he spent babysitting is 12 hours and the number of hours he spent mowing lawns last week is 8 hours.

Step-by-step explanation:
A table is on sale for $289, which is 32% less than the regular price.
What is the regular price?
Answer:
[tex]R = \$903.125[/tex]
Step-by-step explanation:
Given
[tex]Selling\ Price = \$289[/tex]
[tex]Rate = 32\%[/tex]
Required
Determine the regular price (R)
From the question, we understand that:
[tex]R * 32\% = \$289[/tex]
So, we have:
[tex]R * 0.32 = \$289[/tex]
[tex]R = \frac{\$289}{0.32}[/tex]
[tex]R = \$903.125[/tex]
Hence, the regular price is $903.125

Miguel is posting photos on a school website. He has 48 photos, and he is allowed to use 12 pages. He wants to put the same number of photos, p, on each page.
1.) 48p = 12
2.) 12 + p = 48
3.) 12p = 48
4.) 48 = p - 12
Answer:
The answer is 3.)
Step-by-step explanation:
Answer:
3. 12p = 48
Step-by-step explanation:
Start with 12p = 48
Your goal is to find the number of photos, p, that can go on each page. To do this, you need to isolate p (in other words, get p by itself)
Divide both sides by 12 and you end up with:
p = 4
if susan, janice, and melvin take 2.0 hours to walk to their school at a rate of 1.0 m/s, how far is their school from their house?
please help me huhu
Answer:
7.2 km
Step-by-step explanation:
Given that:
Hours taken = 2 hours
Walk rate = 1 m/s
Distance = Speed * time
Time taken in seconds = 2 * 60 * 60 = 7200 s
Hence,
Distance = 1 m/s * 7200s
Distance = 7200 meters
Distance in km = 7200 / 1000 = 7.2 km

You're a contestant on a TV gameshow where you must choose between four identical looking suitcases containing $100, $100, $300, and $400. You start by randomly picking one suitcase. The host then opens the remaining suitcase with the lowest dollar amount. Now, you have the choice to keep your current suitcase or switch to one of the two remaining suitcases. With probability p= 0.7, you keep your original suitcase and open it. Otherwise, you are equally likely to choose either of two the remaining suitcases and open it. You win the money in the suitcase you opened.
Consider these events:
Ai is the event that the first suitcase you choose is worth i dollars.
Hi is the event that the host opens a suitcase worth i dollars.
Wi is the event that you win i dollars.
If you play this game five times, the probability that the event W400 occurs twice in five trials is:_______
Answer:
0.2990 = 29.90%.
Step-by-step explanation:
For each trial, there are only two possible outcomes. Either you win $400, or you do not. Trials are independent. So we use the binomial probability distribution to solve this question.
Binomial probability distribution
The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
In which [tex]C_{n,x}[/tex] is the number of different combinations of x objects from a set of n elements, given by the following formula.
[tex]C_{n,x} = \frac{n!}{x!(n-x)!}[/tex]
And p is the probability of X happening.
Probability of winning $400 in a trial:
1/4 probability of choosing the suitcase containing $400, and in this case, 0.7 probability of keeping it.
3/4 probability of choosing another suitcase. Then, 0.3 of 3/4 probability of changing the suitcase, and 0.5 of 0.3 of 3/4 probability of getting the suitcase containing $400. So
[tex]p = \frac{1}{4}*0.7 + \frac{3}{4}*0.3*0.5 = 0.25*0.7 + 0.75*0.15 = 0.2875[/tex]
If you play this game five times, the probability that the event W400 occurs twice in five trials is:_______
This is P(X = 2) when n = 5. So
[tex]P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}[/tex]
[tex]P(X = 2) = C_{5,2}.(0.2875)^{2}.(0.7125)^{3} = 0.2990[/tex]
The probability is 0.2990 = 29.90%.
