Provide an appropriate response.Jessica wanted to solve the following problem: The price of an item increased by 15%. The amount of the increase was $86. What was the price of the item before the increase? She wrote the following equation: 15% × 86 = x. Will this equation will give her the correct answer? If not, what is the correct equation?

Question

What will be an ideal response?

Answer 1

This equation will not give her the correct answer. The correct equation is  Since there was a 15% increase from the original, unknown price (x), 15% should be multiplied by x, not by the dollar amount of the increase. (Explanations will vary.)
