Final answer:
To calculate the cost per account, use the given time equation and substitute the value of the number of accounts. Round the answer to the nearest cent.
Step-by-step explanation:
To calculate the cost per account, we need to use the given time equation for the interest-bearing checking account product. The time equation is:
0.20(number of accounts) + 0.10(number of statements) + 0.05(number of transactions) + 0.15(number of inquiries)
Given that there are 2,000 interest-bearing accounts, we can substitute this value into the equation:
Cost per account = 0.20(2,000) + 0.10(number of statements) + 0.05(number of transactions) + 0.15(number of inquiries)
Simplifying this equation, we get:
Cost per account = 400 + 0.10(number of statements) + 0.05(number of transactions) + 0.15(number of inquiries)
Now, you can round the answer to the nearest cent to find the cost per account.
