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