Question

A coupon subtracts $5.16 from the price (p) of a shirt. You pay $15.48 for the shirt after using the coupon. What was the original price of the shirt?

Answer 1

20.64

Explanation:

15.48+5.16=20.64

Answer 2

20.64

Explanation:

The original price is p

Subtract the coupon and pay 15.48

p- coupon = 15.48

p -5.16=15.48

Add 5.16 to each side

p-5.16+5.16=15.48+5.16

p =20.64
