310 Warren's savings : Total savings = 3 : 10
Perry's savings = 20 u
20 u = 200
1 u = 200 ÷ 20 = 10
Warren's savings = 27 u
Savings of the other three boys
= 20 u + 25 u + 18 u
= 63 u
Savings that Warren had less than the total of the three other boys
= 63 u - 27 u
= 36 u
= 36 x 10
= $360
Answer(s): $360
