310 Charlie's savings : Total savings = 3 : 10
Perry's savings = 20 u
20 u = 240
1 u = 240 ÷ 20 = 12
Charlie's savings = 21 u
Savings of the other three boys
= 20 u + 22 u + 7 u
= 49 u
Savings that Charlie had less than the total of the three other boys
= 49 u - 21 u
= 28 u
= 28 x 12
= $336
Answer(s): $336
