Answer:
5 hours he can ski.
Step-by-step explanation:
The first step is to write the problem in mathematical language.
So let's call "x" at the time of ski rental.
Now we can do the inequality as follows
Where we are indicating that the total of 65 pesos of ski rental, plus 10 of each hour of rent, should not be greater than 120
Now we only solve the inequality:
We separate the terms that depend on the variable from those that do not depend on it:
we simplify
We divide by the coefficient of the variable
We simplify
So, Jeff must ski no more than 5 hours to spend 120
