- 40% |
+ 30 u |
After |
60% |
130 u |
100% of spending = 240
1% of spending = 240 ÷ 100 = 2.4
40% of spending = 40% x 240 = 96
40% of spending = 30 u of savings
30 u of savings = 96
1 u of savings = 96 ÷ 30 = 3.2
100 u of savings = 100 x 3.2 = 320
Owen's allowance for each month
= 100% of spending + 100 u of savings
= 240 + 320
= $560
Answer(s): $560
