Spending (%) |

100 u |

+ 30% |
- 20 u |
After |
130% |
80 u |
100% of spending = 380
1% of spending = 380 ÷ 100 = 3.8
30% of spending = 30% x 380 = 114
30% of spending = 20 u of savings
20 u of savings = 114
1 u of savings = 114 ÷ 20 = 5.7
100 u of savings = 100 x 5.7 = 570
Howard's allowance for each month
= 100% of spending + 100 u of savings
= 380 + 570
= $950
Answer(s): $950
