Answer 1

To calculate the average amount Brandon spent, sum all his expenditures ($32.25) and divide by the number of transactions (5), resulting in an average of $6.45.

Step-by-step explanation:

To find the average amount spent by Brandon at the hardware store, we need to sum all the amounts he spent throughout the month and then divide by the number of transactions.

Here are the steps to solve the mathematical problem completely:

1. Add up all the amounts spent:
   $3.28 + $6.90 + $5.30 + $12.00 + $4.77 = $32.25
2. Count the number of transactions, which in this case is 5.
3. Divide the total amount spent by the number of transactions to get the average:
   $32.25 ÷ 5 = $6.45

Therefore, the correct option answer in the final answer is B. $6.45.
