Question

A long-distance telephone call costs $0.34 for the first minute and $0.31 for each additional minute. How much does a 25 minute call cost? Round your answer to the nearest dime.

Answer 1

0.31x+0.34                    Create an equation
0.31(25)+0.34                Plug in given information
7.75+0.34                      Multiply then add
$8.09


Now remember it says round to the nearest dime so your answer should be $8.10
