- 30% |
+ 40 u |
After |
70% |
140 u |
100% of spending = 460
1% of spending = 460 ÷ 100 = 4.6
30% of spending = 30% x 460 = 138
30% of spending = 40 u of savings
40 u of savings = 138
1 u of savings = 138 ÷ 40 = 3.45
100 u of savings = 100 x 3.45 = 345
Howard's allowance for each month
= 100% of spending + 100 u of savings
= 460 + 345
= $805
Answer(s): $805
