The total cost (c) in dollars of renting a sailboat for n days is given by the inequality c≥120+60n. what is the maximum number of days for which a sailboat could be rented if the total cost was $360?

For this case we have the following inequality:

c≥120 + 60n

We substitute the value of c = 360 in the inequality:

360≥120 + 60n

We clear the value of n:

360 - 120 ≥ 60n

240 ≥ 60n

240/60 ≥ n

4 ≥ n

Answer:

The maximum number of days for which a sailboat could be rented if the total cost was $ 360 is:

4 days
