Denote the number of miles ridden as `x.` Then $0.65 per mile means that the price will be `0.65*x` for a mileage and the total price including flat rate will be
If Sheena want to spend all her $10, we obtain a linear equation
This is the answer.
It is simple to solve it: subtract 1.75 from the both sides and obtain
then divide both sides by 0.65 and obtain the solution
`x=8.25/0.65 approx 12.7` (miles).
Actually, the text of the problem gives us a linear inequality,
because "Sheena has no more than $10 to spend on a ride."
The solution for this inequality is `xlt=12.7.`
