110 Archie's savings : Total savings = 1 : 10
Eric's savings = 20 u
20 u = 300
1 u = 300 ÷ 20 = 15
Zane's savings = 9 u
Savings of the other three boys
= 20 u + 52 u + 9 u
= 81 u
Savings that Zane had less than the total of the three other boys
= 81 u - 9 u
= 72 u
= 72 x 15
= $1080
Answer(s): $1080
