- 40% |
+ 20 u |
After |
60% |
120 u |
100% of spending = 220
1% of spending = 220 ÷ 100 = 2.2
40% of spending = 40% x 220 = 88
40% of spending = 20 u of savings
20 u of savings = 88
1 u of savings = 88 ÷ 20 = 4.4
100 u of savings = 100 x 4.4 = 440
Xavier's allowance for each month
= 100% of spending + 100 u of savings
= 220 + 440
= $660
Answer(s): $660
