Quizplus · Accepted Answer

The problem states that we need to multiply 8.7 and the sum of a number (which we represent with x) and 10. So the expression would be 8.7(x + 10), which simplifies to 8.7x + 87. Option C matches this expression. The expression for the given phrase is 8.7(x+10) which can be simplified to 8.7x + 87. Therefore, the best choice is C - 8.7(x+10).
