Detailed Explanation
The total cost of the phone call can be represented by the equation: TC = 2.00 + 0.3x, where x is the duration of the call after the first five minutes. In this case, x = 20. Substitute the known values into the equation and solve for the total cost:
TC = 2.00 + 0.3 * 20
TC = 2.00 + 6.00 = 8.00
TC = 2.00 + 0.3 * 20
TC = 2.00 + 6.00 = 8.00
