Question

A coupon subtracts $5.16 from the price (p) of a shirt. You pay $15.48 for the shirt after using the coupon. Write and solve an equation to find the original price of the shirt.

Answer 1

The equation would look like: p - 5.16 = 15.48

because the coupon subtracts 5.16 from p and the price you pay is 15.48

Solve the equation by adding 5.16 to both sides

p = 20.64

The original price of the shirt is $20.64
