Question

You bought a TV with a sale price of $960. If the markdown price was 20% off the original price, what was the original price of the TV?

Answer 1

plz help

Answer 2

You can use a proportion to solve this.

Answer 3

what kind?

Answer 4

Actually, another method is better.

Answer 5

(1.00 - 0.20)P = 960

(0.80)P = 960

P = 960/(0.80) = 1200

Answer 6

^ That's what I was going to say.

Answer 7

btw, where I derived

(1.00 - 0.20)

is 100% - 20%

Answer 8

all good now @aprilsages ?

Answer 9

You can go backward to solve this. Let say x is the cost of the original price. (100%). But the sale price is $960 after you cut 20 percent off the original price. So 100% - 20% = 80%. You're still paying 80 percent of the original price. So by using his equation, \[\large \large (80% \times OriginalPrice) = $960. \] Solve it, and that will give you the original price. Though he already gave you the answer $1200, so the original price is $1200.

Answer 12

\[\large \large (80percent) \times (OriginalPrice) = 960\] Sorry, didn't know the percent sign didn't work.
