True
False

Answer 1

@SageWilson

Answer 2

the discount for 11 is A

Answer 3

but if you wanted to know the cost after the discount, it's b

Answer 4

@SageWilson can u tell me how to do it

Answer 5

Okay, with 10 you'd need to multiply .04 (4% turned into a decimal) by 1,500, which would give you 60, so just multiply 60 by 20.

Sure

Answer 6

ok for 10 i got 1,2000 so do i just round it to the 1,230 @SageWilson

Answer 7

for 11, you change the percentage into a decimal and multiply by the original cost. That gives you the price of how much is being discounted. If you want to find the new price, you subtract the 3.06 by the original price.

Answer 8

yes Phagey

Okay for 11 you'd need to multiply .18 by 16.98, this would give you 3.05, so to find your answer just subtract 3.05 by 16.98.

Answer 9

so its 13.93 @SageWilson

Answer 10

so the 13.93 is the discount

Answer 11

that'd the price after the discount, but it's asking how much you are going to take off. thats 3.06

Answer 12

actually it's 13.92, @originalgroupie_ did it right by rounding 3.05 to 3.06

Answer 13

that's*

Answer 14

Forget what I just said, @originalgroupie_ is correct, I was just confused by "What is the discount" I wasn't sure if it was asking for the discount price or the difference.

Answer 23

13 is C

Answer 24

you multiply .05 by 28 and it is the closest to the total cost.

Answer 25

14 is true

Answer 26

actually 14 is false. 10% as a deciaml would be .10 not .01, .01 is 1% as a decimal.
