Reasoning: This word problem is telling us that $60 is 120% of her budget. To find her monthly budget, we need to find 100% of her budget. To get 100% we need to get rid of 20%.
This means the first step in this problem is finding 20% of 60. 20% of 60 is 12.
After you get 12, subtract it from 60. 60 - 12=48. 48 is her monthly budget.
