14 Xavier's savings : Total savings = 1 : 4
Luis's savings = 28 u
28 u = 700
1 u = 700 ÷ 28 = 25
Xavier's savings = 17 u
Savings of the other three boys
= 28 u + 6 u + 17 u
= 51 u
Savings that Xavier had less than the total of the three other boys
= 51 u - 17 u
= 34 u
= 34 x 25
= $850
Answer(s): $850
