If Mr. Russo spends $450 on food, what is his total monthly budget?
a. $3,000
b. $6,750
c. $2,550
d. $4,500

To calculate Mr. Russo's total monthly budget, we can first determine the percentage of his budget that food represents.

Food represents 15% of his budget, and $450 is the amount allocated for food.

So, we can set up the equation:
15% of Total Budget = $450

Let x be the total monthly budget:
0.15x = $450
x = $450 / 0.15
x = $3,000

Therefore, Mr. Russo's total monthly budget is $3,000.

Therefore, the correct answer is:
a. $3,000
