Answer:
D, $100.00
Step-by-step explanation:
1. Find out how much what each percent is out of 400
Food - 20% of 400 = 80
Entertainment - 18% of 400 = 72
Savings - 15% of 400 = 60
Misc - 12% of 400 = 48
Clothes - 10% of 400 = 40
2. Subtract the money from 400
400 - 80 = 320
320 - 72 = 248
248 - 60 = 188
188 - 48 = 140
140 - 40 = 100
3. All we have left is 100, so he spent $100 dollars on rent.
