Question

The original price of a pair of pants is $28.80. Al buys them on sale for 25% off. The store gives an additional 10% off of the sale price. How much does Al pay for the pants.

Answer 1

28.8((100-25)/100)((100-10)/100)

28.8(75/100)(90/100)

28.8(.75)(.9)

$19.44

Answer 2

Original price : $28.80

25% off : Multiply 28.8 by 1/4

28.8 × 1/4 = 7.2

So, $7.20 are taken off of $28.80.

$28.80 - $7.20 = $21.60

Then, you get an additional 10% off.

10% off is 1/10 off of the already discounted price.

So, multiply 21.6 with 1/10


Turn 1/10 into .1

21.6 × 0.1 = 2.16

So, that's $2.16 off of the already discounted price.

So then you do $21.60 - $2.16

$21.60 - $2.16 = $19.44

So, Al pays $19.44 for the pants.
