| Before |
4 u + 88 |
4 u |
| Change |
- 1 u - 22 |
- 3 u |
| After |
3 u + 66 |
1 u |
25% =
25100 =
14 75% =
75100 =
34Total amount that Julian and Tiffany had in the end
= 3 u + 66 + 1 u
= 4 u + 66
4 u + 66 = 390
3 u + 1 u = 390 - 66
4 u = 324
1 u = 324 ÷ 4 = 81
Amount that Julian had in the end
= 3 u + 66
= 3 x 81 + 66
= 243 + 66
= $309
