- 40% |
+ 10 u |
After |
60% |
110 u |
100% of spending = 410
1% of spending = 410 ÷ 100 = 4.1
40% of spending = 40% x 410 = 164
40% of spending = 10 u of savings
10 u of savings = 164
1 u of savings = 164 ÷ 10 = 16.4
100 u of savings = 100 x 16.4 = 1640
Valen's allowance for each month
= 100% of spending + 100 u of savings
= 410 + 1640
= $2050
Answer(s): $2050
