A movie ticket cost me $5.60 after a 20% coupon. What was the original price of the ticket?

7.00

Step-by-step explanation:

discount = original price * 20%

final price = original price - discount

Substituting the equation for discount

final price = original price - original price*20%

Factoring out the original price

final price = original price (1-20%)

Changing to decimal form and putting the final price

5.60 = original price (1-.2)

5.60 = original price (.8)

Divide by each side by. 8

5.6/.8 = original price (.8) /.8

7 = original price
