The difference in the amounts between Daniel and his cousin at first and in the end remains unchanged after each received an equal amount of allowance.
Difference in the amounts between Perry and his cousin
= 4 u - 1 u
= 3 u
3 u = 218 - 17
3 u = 201
1 u = 201 ÷ 3 = 67
Allowance that each of them received
= 1 u - 17
= 67 - 17
= $50
Answer(s): $50
