Since both Zane and John spent an equal amount of money every day, the difference in their amounts remains the same.
Difference in their amounts
= 5 u - 1 u
= 4 u
4 u = 132
1 u = 132 ÷ 4 = 33
Amount that Zane had in the end
= 5 u
= 5 x 33
= $165
Amount that Zane had spent
= 228 - 165
= $63
Amount that each of them spent every day
= 63 ÷ 9
= $7
Answer(s): $7
