Justin bought a shirt at 12% off and received an additional membership discount of 7$. If the T-shirt cost him 15$, what was the original price of the T-shirt?

Answer:the original price of the shirt is $25

Step-by-step explanation:

Let x represent the initial price of the shirt.

Justin bought a shirt at 12% off. This means that the discount off the original price of the shirt would be

12/100 * x = 0.12 * x = 0.12x

The price of the shirt with the discount off would be

x - 0.12x = 0.88x

He received an additional membership discount of 7$. This means that the final price of the shirt would be

0.88x - 7

If the T-shirt cost him $15, it means that

0.88x - 7 = 15

0.88x = 15 + 7 = 22

x = 22/0.88 = 25

Step-by-step explanation:

If you are saving 12%, you are still spending 88%. Our equation will be, in words,

88% of the original price, x, minus $7 is $15. In equation form:

.88x - 7 = 15 so

.88x = 25 so

x = $28.41
