Answer:
10
Explanation:
Let's denote the number of wire transfers as "x". For checking account A, the total cost would be:
Total cost for A = Monthly service fee + (Wire transfer fee * Number of transfers)
Total cost for A = $20 + ($3 * x)
For checking account B, the total cost would be:
Total cost for B = Monthly service fee + (Wire transfer fee * Number of transfers)
Total cost for B = $30 + ($2 * x)
Now we want to find out how many transfers "x" would make the two accounts cost the same. So we set up an equation where the total costs are equal:
$20 + ($3 * x) = $30 + ($2 * x)
Now, let's solve for "x":
$3 * x - $2 * x = $30 - $20
$x = $10
So, the two accounts would cost the same when there are 10 wire transfers. Therefore, the answer is:
A. 10
