Question

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?

Answer 1

Below is the solution for the problem above:

Given: 
Let x be the price of the pizza 
$5 for the coupon 
15% discount 

Solution 
x is the price of the pizza. If coupon is applied before:
 (x-5)0.85=0.85x-0.85*5
 
if it is applied after: 0.85x-5
 
Therefore, the difference between the two is 0.15*5=0.75

The answer is USD 0.75
