PLease help . . . . . . . .

Answer 1

Traveling
`m` miles on this taxi costs

`c=2.5+3.25m`

In fact, we spend 2.50 no matter what, and then we add 3.25 (i.e. the cost of a mile) multiplied by the number of miles.

This quantity has to be less than or equal to 61, so we have

`2.5+3.25m\leq 61`

Solving for
`m`, we start by subtracting 2.5 from both sides:

`3.25m\leq 58.5`

Then, we divide both sides by 3.25:

`m\leq 18`
