The difference in the amounts between Jeremy and his sister at first and in the end remains unchanged after each received an equal amount of allowance.
Difference in the amounts between Perry and his sister
= 5 u - 1 u
= 4 u
4 u = 183 - 23
4 u = 160
1 u = 160 ÷ 4 = 40
Allowance that each of them received
= 1 u - 23
= 40 - 23
= $17
Answer(s): $17
