Answer 1

Brent spends $63 on utilities each month, which is 15% of his total monthly bills of $420.

Step-by-step explanation:

To find out how much Brent spends on utilities, we need to calculate 15% of his total monthly bills of $420. To do this, we can convert the percentage to a decimal by dividing 15 by 100, which gives us 0.15. Then, we multiply $420 by 0.15 to get the amount spent on utilities.

Let's do the calculation:

0.15 × $420 = $63.

Therefore, Brent spends $63 on utilities each month, which corresponds to answer option a) $63.
