25 Brandon's savings : Total savings = 2 : 5
Oscar's savings = 35 u
35 u = 700
1 u = 700 ÷ 35 = 20
Ahmad's savings = 19 u
Savings of the other three boys
= 35 u + 3 u + 38 u
= 76 u
Savings that Ahmad had less than the total of the three other boys
= 76 u - 19 u
= 57 u
= 57 x 20
= $1140
Answer(s): $1140
