Question

A store decides on the cost of a pair of jeans by tripling their cost and then decreasing it by $15. The cost of the jeans in the store is $105. What does the store pay for the jeans?​

Answer 1

40$

Explanation:

if we write it out in an equation, we get

105(final price) = 3x (triple the value they produce it for) - 15 (they degrease it by 15)

subtract 15 from both sides, you get 120 = 3x

divide both sides by 3, you get 40 = x
