310 Tommy's savings : Total savings = 3 : 10
Cody's savings = 25 u
25 u = 525
1 u = 525 ÷ 25 = 21
Tommy's savings = 21 u
Savings of the other three boys
= 25 u + 17 u + 7 u
= 49 u
Savings that Tommy had less than the total of the three other boys
= 49 u - 21 u
= 28 u
= 28 x 21
= $588
Answer(s): $588
