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

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
