- 10% |
+ 40 u |
After |

140 u |
100% of spending = 220
1% of spending = 220 ÷ 100 = 2.2
10% of spending = 10% x 220 = 22
10% of spending = 40 u of savings
40 u of savings = 22
1 u of savings = 22 ÷ 40 = 0.55
100 u of savings = 100 x 0.55 = 55
Daniel's allowance for each month
= 100% of spending + 100 u of savings
= 220 + 55
= $275
Answer(s): $275
