Question

Mr. Sustar, Dr. Leong, and Mrs. Wolbert's classes raised money for Mathematicians without Borders

in the ratio of 1:6:5. In total, they raised $480. How much did each class raise?

Answer 1

$40 for Mr. Sustar's class, $240 for Dr. Leong's class, $200 for Mrs. Wolbert's class

Explanation:

m + 6m + 5m = 480

12m = 480

m = 40, so 6m = 240 and 5m = 200
