A phone company charges for \(\$2\)the first five minutes of a phone call and 30 cents per minute thereafter. If Bill makes a phone call that lasts 25 minutes, what will be the total cost of the phone call?

\(\$8.00\)

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:
 \(TC = \$2.00 + \$0.3 \times 20\)
 \(TC=\$2.00\)

 \(TC = \$8.00\)
