Answer:
B. $5.58
Step-by-step explanation:
In order to find the amount of income earned, we can set up an equation using a variable for the number of checks and the minimum balance:
Income earned = (.008)b - $0.10c - $2.00, where b = the minimum balance and c = the number of checks.
Since the customer writes 21 checks, c = 21 and maintains a minimum balance of $1,210, b = 1210, we can fill in the variables and solve the equation:
Income earned = (.008)(1210) - (0.10)(21) - 2 or 9.69 - 2.10 - 2 = $5.58
