Neave and Daniel were given some allowances each. If Neave spent $14 each day and Daniel spent $28 each day, Neave would still have $1234 left when Daniel spent all his allowance. If Neave spent $28 each day and Daniel spent $14 each day, Neave would still have $58 left when Daniel spent all his allowance.

(a)
Simplify the ratio.
14 : 28 = 1 : 2
The allowance that Daniel had at first is the same for Case 1 and Case 2.
1 p = 2 u
2 p = 4 u
The allowance that Neave had at first is the same for Case 1 and Case 2.
4 u + 58 = 1 u + 1234
4 u - 1 u = 1234 - 58
3 u = 1176
1 u = 1176 ÷ 3 = 392
Allowance that Neave received
= 1 u + 1234
= 392 + 1234
= $1626
(b)
Allowance that Daniel received
= 2 u
= 2 x 392
= $784
Answers: (a) $1626; (b) $784
