310 Brandon's savings : Total savings = 3 : 10
Michael's savings = 20 u
20 u = 240
1 u = 240 ÷ 20 = 12
Ivan's savings = 14 u
Savings of the other three boys
= 20 u + 15 u + 21 u
= 56 u
Savings that Ivan had less than the total of the three other boys
= 56 u - 14 u
= 42 u
= 42 x 12
= $504
Answer(s): $504
