310 Ivan's savings : Total savings = 3 : 10
Cody's savings = 25 u
25 u = 900
1 u = 900 ÷ 25 = 36
Ivan's savings = 24 u
Savings of the other three boys
= 25 u + 7 u + 24 u
= 56 u
Savings that Ivan had less than the total of the three other boys
= 56 u - 24 u
= 32 u
= 32 x 36
= $1152
Answer(s): $1152
