A car can be rented for $95 per week plus $0.95 per mile. How many miles can be driven if you have at most $380 to spend for weekly transportation? The car should be driven ....... miles a week?

Respuesta :

We have the next inequality

[tex]95+0.95x\le380[/tex]

where x is the number of miles.

Then we solve the inequality

[tex]\begin{gathered} 0.95x<380-95 \\ \end{gathered}[/tex]

[tex]\begin{gathered} 0.95x\le285 \\ x\le\frac{285}{0.95} \\ x\le300 \end{gathered}[/tex]

The car should be driven 300 miles a week
