Final answer:
The total bill will be $26.00.
Step-by-step explanation:
To calculate the total bill, we need to add the flat fee of $20 to the cost of the calls. Since each call costs 3 cents, the total cost of the calls will be $0.03 multiplied by the number of calls.
In this case, there were 200 calls, so the cost of the calls will be $0.03 * 200 = $6.00.
Adding the flat fee of $20 to the cost of the calls, the total bill will be $20 + $6.00 = $26.00.
