You go to a restaurant and order $137.61 worth of food. You decide to tip the waiter

18%. You also have to pay a tax of 6.5% on the original bill. What is the final cost of the meal?

Step by Step

Answers

Answer 1

Answer:

I got 2

Step-by-step explanation:

Answer 2

The final cost of meal is $171.35

What is unitary method?

The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Given:

price of food = $137 . 61

Tip = 18%

tax = 6.5%

Now, price after giving tip

=137.61 x 0.18

= 24.7698

and, after tax

=137.61 x 0.065

=8.94465

Hence, final cost of meal = 137.61 + 24.7698 + 8.94465 = $171.35

Benita buys 2 shirts for the same price, s. The sales tax rate is 6.5%.


Write an expression to represent the total cost of the shirts in two different ways.


Enter the correct answers in the boxes.

Answers

Answer:

2S + 0.065(2S)

Step-by-step explanation:

Since S is the price of a shirt, the price of two shirts would be 2 x S = 2S

a tax is a compulsory sum levied on goods and services. tax increases the price of a good

The price of the 2 shirts would increase by the amount of tax ; 0.065(2S)

This gives = 2S + 0.065(2S)

Alternatively, since two shirts were purchased, the amount of tax would be twice 0.065 - 0.13 - S + S + 0.13S

We want to write two expressions that represent the total cost of the shirts, the expressions are:

Cost = P*(1.065) +  P*(1.065)

cost = P*2.13

We know that Benita buys two shirts for the same price, P.

Then at this moment. the total cost is just:

cost = 2*P

Now we apply a 6.5% tax, then the price increases by 6.5%, this is written as:

P' = P*(1 + 6.5%/100%) = P*(1.065)

Then the total cost is twice that amount, written as:

Cost = P*(1.065) +  P*(1.065)

This can be one of the two expressions.

Now to get the other expression, we just simplify the above one:

cost = 2*P*(1.065) = P*2.13

A game show contestant cannot spend more than $100 on $0.79 cans of beans and $3.59 boxes of cereal. Which inequality represents the situation, where b is the number of cans of beans and c is the number of boxes of cereal?

Answers

Answer:

i believe it would be 0.79b + 3.59c [tex]\leq[/tex] 100

Step-by-step explanation:

the price of the number of cans of beans added to the number of boxes of cereal must be less than or equal to $100

0.79b represents the price of the beans multiplied by the amount of cans the contestant buys, and 3.59c represents the price of the cereal multiplied by the amount of boxes the contestant buys

A right triangle with the side AB as a length of 35 cm and another side length BC with 12 cm. What is the hypotenuse length of the right triangle?

Answers

The formula to find the hypotenuse is a^2 + b^2 = c^2. Let’s call side AB, “a” and call side BC, “b”. Now “a” = 35 cm and “b” = 12 cm. Using the formula, you square (multiply the number by itself) “a” and “b” then add them together. This would look like 35^2 + 12^2 =c^2. When you do the multiplication it ends up as 1,225 + 144 = c^2. Add 1,225 and 144 together to get 1,369 = c^2. Last step is to square root both sides to get 37 = c. So the hypotenuse of this triangle would be 37.

Rectangle ABCD is graphed in the coordinate plane. The following are the vertices of the rectangle: A(-2, 1),B(3,1), C (3,4) D(-2,4). What is the perimeter of rectangle ABCD?

Answers

Answer:

16 units

Step-by-step explanation:

Rectangle perimeter = width + width + height + height = 2 (width) + 2 (height)

To find the length of one of the sides of the rectangle, I am going to find the distance between points A and B.

The y-xoordinates are the same for A and B, so this is a horizontal line. This means we are measuring the width of the rectangle.

To find the distance, we take 3 - -2 = 5 units

So the width of the rectangle is 5 units.

We can do the same thing to find the height of the rectangle using B and C.

They have the same x-coordinates, so the distance between them will be the difference in the y-coordinates.

4 - 1 = 3, so the height of the rectangle is 3.

Finally, to find the perimeter, we do 2(5) + 2(3) = 16 units

The perimeter of the rectangle is 16 units.

I hope this helps!

Which expression doesn't belong? Why does it not belong? A. 7.9x B. 7.9 · (-10) C. 7.9 + x D. - 79

When I think of a number, double it, then add 7, I get 25. What number did I think of? ( Hint: Let the number be x)o

Answers

Hey there!

The answer is [tex]9[/tex]

We will start by forming an equation to solve this.

So we are starting with a number, [tex]x[/tex], then doubling it and adding [tex]7[/tex], which gives us 25.

So:

[tex]2x+7=25[/tex]

Now we solve this equation:

[tex]2x+7=25[/tex]

[tex]2x=18[/tex]

[tex]x=9[/tex]

Answer:

X = 9

Step-by-step explanation:

If you take 9, then double it, you get 18. 9+9 = 18. Then, you would add 7. 18 plus 7 is 25.

Hence, the answer to this problem is 9.

Next, you do exponents
-10^2 or -10 * -10 = 100

8 is 80% of what number?

Answers

Answer: 10

Step-by-step explanation:

80/100 of 10

0.8 × 10 = 8

8 is 80% of 10

A value or ratio that may be stated as a fraction of 100 is referred to as a percentage in mathematics. If we need to calculate a percentage of a number, we should divide it by its entirety and then multiply it by 100.

To find a number such that, it's 80% is 8.

Let the number be x

80%x =8

This forms an equation in one variable which can be solved by transposition.

[tex]80x/100=8[/tex]

On multiplying 100 both sides,

[tex]80x=800[/tex]

On dividing 80 both sides,

x=10

Thus,  80% of 10 is 8.
