Asher and Zane were given some allowances each. If Asher spent $14 each day and Zane spent $42 each day, Asher would still have $2532 left when Zane spent all his allowance. If Asher spent $42 each day and Zane spent $14 each day, Asher would still have $68 left when Zane spent all his allowance.

(a)
Simplify the ratio.
14 : 42 = 1 : 3
The allowance that Zane had at first is the same for Case 1 and Case 2.
1 p = 3 u
3 p = 9 u
The allowance that Asher had at first is the same for Case 1 and Case 2.
9 u + 68 = 1 u + 2532
9 u - 1 u = 2532 - 68
8 u = 2464
1 u = 2464 ÷ 8 = 308
Allowance that Asher received
= 1 u + 2532
= 308 + 2532
= $2840
(b)
Allowance that Zane received
= 3 u
= 3 x 308
= $924
Answers: (a) $2840; (b) $924
