310 Brandon's savings : Total savings = 3 : 10
Rael's savings = 25 u
25 u = 800
1 u = 800 ÷ 25 = 32
Sam's savings = 7 u
Savings of the other three boys
= 25 u + 17 u + 21 u
= 63 u
Savings that Sam had less than the total of the three other boys
= 63 u - 7 u
= 56 u
= 56 x 32
= $1792
Answer(s): $1792
