- 20% |
+ 10 u |
After |
80% |
110 u |
100% of spending = 450
1% of spending = 450 ÷ 100 = 4.5
20% of spending = 20% x 450 = 90
20% of spending = 10 u of savings
10 u of savings = 90
1 u of savings = 90 ÷ 10 = 9
100 u of savings = 100 x 9 = 900
Daniel's allowance for each month
= 100% of spending + 100 u of savings
= 450 + 900
= $1350
Answer(s): $1350
