Respuesta :

Given the equation:

[tex]C=4+0.10t[/tex]

where 'C' is the charge in dollars and 't' is the time in minutes, if we want to know what is the charge for 20 minutes, we have to make t = 20 and solve for C:

[tex]\begin{gathered} t=20 \\ \Rightarrow C=4+0.10(20)=4+2=6 \\ C=6 \end{gathered}[/tex]

therefore, the charfe to rent a paddle boat for 20 minutes is 6 dollars
