310 Dylan's savings : Total savings = 3 : 10
Charlie's savings = 10 u
10 u = 180
1 u = 180 ÷ 10 = 18
Dylan's savings = 33 u
Savings of the other three boys
= 10 u + 56 u + 11 u
= 77 u
Savings that Dylan had less than the total of the three other boys
= 77 u - 33 u
= 44 u
= 44 x 18
= $792
Answer(s): $792
