- 20% |
+ 10 u |
After |
80% |
110 u |
100% of spending = 440
1% of spending = 440 ÷ 100 = 4.4
20% of spending = 20% x 440 = 88
20% of spending = 10 u of savings
10 u of savings = 88
1 u of savings = 88 ÷ 10 = 8.8
100 u of savings = 100 x 8.8 = 880
Flynn's allowance for each month
= 100% of spending + 100 u of savings
= 440 + 880
= $1320
Answer(s): $1320
