Question

Will someone check my answer please?! :)

You have a coupon good for $5 off the price of any large pizza. You also get a %15 discount on any pizza if you show your student ID. How much more would you pay for a large pizza if the cashier applies the coupon first?
My answer: $.75

Answer 1

If x = price of pizza, then x-5 would be the coupon applied first, now for the 15% discount: .85(x-5) = .85x - 4.25

If discount is applied first then .85x now minus the coupon .85x - 5

It appears to me the bargain is the latter.

Answer 2

In other words you pay 75 cents more when the coupon is applied firs.

Answer 3

So am I right?

Answer 4

.75 is correct, but it less not more as the problem was worded.

Answer 5

Have the student 15% discount apploied first then use the coupon. lol.

Answer 6

Alright thanks.

Answer 7

Look at it this way, lets say the large pizza is priced at $12.00

Scenario 1. Use coupon first, pizza is now $7.00 , now apply 15% discount
pizza is now .85($7.00) or $5.95
Scenario 2. Use discount first, pizza is .85(12.00) or $10.20 now apply the $5.00 coupon
$10.20 - $5.00= $5.20

Which is the bargain? and the bargain is .75 less.
