Question

Maria and Mark were saving money for their table and house at a ratio of 4:7. Maria had 186 dollars less than Mark. How much money did they save together?

Answer 1

$682

Explanation:

The sum of ratio units is 4+7 = 11. The difference is 7 -4 = 3. That is, the sum of amounts saved is 11/3 times the difference of amounts saved:

(11/3)($186) = $682

Together, Maria and Mark saved $682.
