Question

James works in a sporting goods store and earns $324 a week and 5% of his sales. One week James earned $432. What were his sales that week?

Answer 1

His sales that week were $2,160.

Explanation:

First, you have to subtract $324 from the amount he earned that week, to find the 5% he got from sales:

$432-$324=$108

Now, you know that he received $108 that represent 5% of his sales and you can use a rule of three to find the amount that represents 100% which would be his sales that week:

5% → 108

100% → x

x=(100*108)/5=2160

According to this, the answer is that his sales that week were $2,160.
