If you want to buy an item in a store that costs $15 and is on sale for 15% off, then how much would the item actually cost you after the discount? Round to the nearest cent.

It would cost you $12.75.

Step-by-step explanation:

Model an equation, using c as the initial cost variable and x as the final cost, and then solve for x.

hope it

step-by-step explanation:

x^(1/6) · x^(1/6) · x^(1/6)   ·x^(1/6) = x^(4/6)   since we add the exponents

4/6 can be simplified to 2/3

the simplified form is x^(2/3)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
