Spending (%) |
Savings (u) |

100 u |
Change |
+ 30% |
- 10 u |
After |
130% |
90 u |
100% of spending = 320
1% of spending = 320 ÷ 100 = 3.2
30% of spending = 30% x 320 = 96
30% of spending = 10 u of savings
10 u of savings = 96
1 u of savings = 96 ÷ 10 = 9.6
100 u of savings = 100 x 9.6 = 960
Asher's allowance for each month
= 100% of spending + 100 u of savings
= 320 + 960
= $1280
Answer(s): $1280
