Answer:
The total income is $1,500.
Explanation:
$300 / 20% = $15 [ budget percent x 15 = budget amount in dollars]
Housing: 10 x 15 = $150
Food: 30 x 15 = $450
Fuel: 15 x 15 = $225
Clothing: 20 x 15 = $300
Health: 15 x 15 = $225
Miscellaneous: 10 x 15 = $150
Total Income: 150+450+225+300+225+150 = $1500
