310 Caden's savings : Total savings = 3 : 10
Cole's savings = 40 u
40 u = 880
1 u = 880 ÷ 40 = 22
Oliver's savings = 18 u
Savings of the other three boys
= 40 u + 5 u + 27 u
= 72 u
Savings that Oliver had less than the total of the three other boys
= 72 u - 18 u
= 54 u
= 54 x 22
= $1188
Answer(s): $1188
