to rent a booth at a County Fair cost $42 per day plus a one-time equipment fee of $85 find the number of days mr. Jones rented a booth if he paid a total of $337
[tex]\begin{gathered} 42\text{ D+85=337, where D is the number of day. We must find D. Then,} \\ 42\text{ D = 337 - 85} \\ 42\text{ D = }252 \\ D=\frac{252}{42},\text{ hence,} \\ D=6 \end{gathered}[/tex]
