Albert and Wesley were given some allowances each. If Albert spent $12 each day and Wesley spent $24 each day, Albert would still have $1018 left when Wesley spent all his allowance. If Albert spent $24 each day and Wesley spent $12 each day, Albert would still have $46 left when Wesley spent all his allowance.

(a)
Simplify the ratio.
12 : 24 = 1 : 2
The allowance that Wesley had at first is the same for Case 1 and Case 2.
1 p = 2 u
2 p = 4 u
The allowance that Albert had at first is the same for Case 1 and Case 2.
4 u + 46 = 1 u + 1018
4 u - 1 u = 1018 - 46
3 u = 972
1 u = 972 ÷ 3 = 324
Allowance that Albert received
= 1 u + 1018
= 324 + 1018
= $1342
(b)
Allowance that Wesley received
= 2 u
= 2 x 324
= $648
Answers: (a) $1342; (b) $648
