Gabby purchased a pair of ear phones online for $12. she purchased the ear phones at 60% of the store price. what was the store price of the ear phones ?

The answer of your question is: $20

Step-by-step explanation:

Data

price $12

60% of the store price

Solve it using an inverse rule of three

                           $12  60%

                             x    100%

        x = 100(12) / 60 = $20

the answer is (4,3)

since the rule for r0, 90º is (-y,x) and it was already applied to form the image, all you have to do is reverse the answer using this formula.
