90 u |
100% of savings = 250
1% of savings = 250 ÷ 100 = 2.5
40% of savings = 40% x 250 = 100
40% of savings = 10 u of spending
10 u of spending = 100
1 u of spending = 100 ÷ 10 = 10
100 u of spending = 100 x 10 = 1000
Jenson's allowance for each month
= 100% of savings + 100 u of spending
= 250 + 1000
= $1250
Answer(s): $1250
