During a sale, every item in a store is 80% of its regular price.


1. If the regular price of a T-shirt is $10, what is its sale price?

2. During a sale, every item in a store is 80% of its regular price. The regular prices of five items are shown here. Find the sale price of each item.


P.S. For the 2nd question see the file.

P.P.S. WILL GIVE BRAINLIEST!

Answers

Answer:

For #1 the answer is $2

Step-by-step explanation:

This is because 80% of 10 is 8, so then you subtract that and get 2. For #2 the answer to item 1 is $0.8, item 2 is $3.2, item 3 is $8, item 4 is $44, and item 5 is $96

Answer/Step-by-step explanation:

During a sale, every item in a store is 80% of its regular price

[1] if a regular T-shirt is $10, what is its sale price?

80% x 10 = 8

10 - 8 = 2.

Hence if a regular T-shirt is $10, the sale price will be $2.

[2] The regular prices of five items are shown here. Find the sale price of each item.

Item 1:   1x80%=0.8

Item 2: 4x80%=3.20

Item 3: 10x80%=8

Item 4: 55x80%=44

Item 5: 120x80%=96

divide both by 8

x=8

I got 1.5 = x. Do -16 = -8x -4 then you add the -4 to the -16 making it -12 = -8x the. You divide -8 to both sides and you will get 1.5 = X

Heya!

So the key is at the top. What I mean by the Key is a=1 b=2 c=3 d=4 e=5 and f=0. You use those numbers and plug them into the associated letters in the problems below. For example, question one with the numbers in it would be, (I might be wrong on this, I apologize)

[tex] \frac{0 + 3^{2} - 2 }{0 - 3} [/tex]

You would then solve the equation, and whatever answer you get for that equation would go with the corresponding numbers and letters on the left.

So for example, if your answer to the first one for example is 7, you would type A. You would then do the same for question 2, 3, and 4, which should reveal the four letter code for you to continue :))

Christopher wants to join a basketball team but each member has to pay a $300 yearly membership fee. The organization will allow Christopher to pay $15 monthly until he pays off his membership. However, he must pay a $150 deposit down first. Christopher puts the $150 deposit down and will begin paying the $15 fee monthly on April 1st. write a linear equation that will help us find out how many months it will take for Christopher to pay off his entire membership.

Answers

Answer:

10 months

Step-by-step explanation:

this is the equation to determine the number of months it will take to pay the full membership fee

300 = 15x + 150

solve for x

subtract 150 from both sides

150 = 15x

divide both sides by 15

10 = x

it will yake 10 months to pay off the membership
