,

• Let Charlies ride be equal to ,t minutes, long

,

• This is a linear function representing the total bill for Charlies ride as follows :

`3\text{ + }0.11t=13.56\text{ }`

Therefore , solving for t , we get that t =

`\begin{gathered} 0.11t\text{ = 13.56 - 3 } \\ 0.11t\text{ = 10.56 } \\ \frac{0.11t}{0.11\text{ }}=\text{ }(10.56)/(0.11) \\ \therefore\text{ t = 96 minutes} \end{gathered}`

• t = 96 minutes ,

• This means that Charlie travelled for, 96 minutes ,.

,
