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

a. is correct

(x,y) it'll always be like that.

in this case x is grams and y is ounces.

if there were numbers there, like (5,3)

x would be 5 and y would be 3.
