Wesley and Eric were given some allowances each. If Wesley spent $14 each day and Eric spent $42 each day, Wesley would still have $950 left when Eric spent all his allowance. If Wesley spent $42 each day and Eric spent $14 each day, Wesley would still have $54 left when Eric spent all his allowance.

(a)
Simplify the ratio.
14 : 42 = 1 : 3
The allowance that Eric had at first is the same for Case 1 and Case 2.
1 p = 3 u
3 p = 9 u
The allowance that Wesley had at first is the same for Case 1 and Case 2.
9 u + 54 = 1 u + 950
9 u - 1 u = 950 - 54
8 u = 896
1 u = 896 ÷ 8 = 112
Allowance that Wesley received
= 1 u + 950
= 112 + 950
= $1062
(b)
Allowance that Eric received
= 3 u
= 3 x 112
= $336
Answers: (a) $1062; (b) $336
