$336 |
The total amount that Albert and Zane had remains unchanged.
Total amount in the end
= 2 u + 1 u
= 3 u
3 u = 336
1 u = 336 ÷ 3 = 112
Amount that Zane has in the end
= 2 u
= 2 x 112
= $224
Amount that Albert has in the end
= 1 u
= $112
7 p = 1 u = 112
1 p = 112 ÷ 7 = 16
Amount that Albert gave to Zane
= 1 p
= 1 x 16
= $16
Amount that Zane had at first
= 224 - 16 + 24
= $232
Answer(s): $232
