310 Pierre's savings : Total savings = 3 : 10
Simon's savings = 40 u
40 u = 440
1 u = 440 ÷ 40 = 11
Cody's savings = 9 u
Savings of the other three boys
= 40 u + 14 u + 27 u
= 81 u
Savings that Cody had less than the total of the three other boys
= 81 u - 9 u
= 72 u
= 72 x 11
= $792
Answer(s): $792
