110 Elijah's savings : Total savings = 1 : 10
Pierre's savings = 5 u
5 u = 175
1 u = 175 ÷ 5 = 35
Elijah's savings = 3 u
Savings of the other three boys
= 5 u + 16 u + 6 u
= 27 u
Savings that Elijah had less than the total of the three other boys
= 27 u - 3 u
= 24 u
= 24 x 35
= $840
Answer(s): $840
