14 Michael's savings : Total savings = 1 : 4
Henry's savings = 20 u
20 u = 300
1 u = 300 ÷ 20 = 15
Luis's savings = 17 u
Savings of the other three boys
= 20 u + 14 u + 17 u
= 51 u
Savings that Luis had less than the total of the three other boys
= 51 u - 17 u
= 34 u
= 34 x 15
= $510
Answer(s): $510
