Jeremy and Wesley were given some allowances each. If Jeremy spent $29 each day and Wesley spent $58 each day, Jeremy would still have $1141 left when Wesley spent all his allowance. If Jeremy spent $58 each day and Wesley spent $29 each day, Jeremy would still have $97 left when Wesley spent all his allowance.

(a)
Simplify the ratio.
29 : 58 = 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 Jeremy had at first is the same for Case 1 and Case 2.
4 u + 97 = 1 u + 1141
4 u - 1 u = 1141 - 97
3 u = 1044
1 u = 1044 ÷ 3 = 348
Allowance that Jeremy received
= 1 u + 1141
= 348 + 1141
= $1489
(b)
Allowance that Wesley received
= 2 u
= 2 x 348
= $696
Answers: (a) $1489; (b) $696
