- 40% |
+ 10 u |
After |
60% |
110 u |
100% of spending = 140
1% of spending = 140 ÷ 100 = 1.4
40% of spending = 40% x 140 = 56
40% of spending = 10 u of savings
10 u of savings = 56
1 u of savings = 56 ÷ 10 = 5.6
100 u of savings = 100 x 5.6 = 560
Jenson's allowance for each month
= 100% of spending + 100 u of savings
= 140 + 560
= $700
Answer(s): $700
