Marcel made an error when he used the distributive property to solve the problem shown. Which sentence describes the error? In Step 2, 90 should be multiplied by the quantity 10 – 12, not by 10. 10 was substituted for x at the wrong step. In Step 1, the expression should be x(90 – 12) not 90(x– 12). There should be no parentheses in Step 1. It should be 90 • x – 12.
