A phone company charges 2 dollars for the first five minutes of a phone call and 30 cents per minute thereafter. If Malik makes a phone call that lasts 25 minutes, what will be the total cost of the phone call?
8.00 dollars.
8.50 dollars.
9.00 dollars.
9.50 dollars.
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
