How long can you rent something for the max time?

Question

Q: The rental company employee says it is a flat fee of $39 to rent a small auger and an additional $15 per hour used. Also, you may only keep the small auger for a maximum of 22 hours. How much will it cost for you to rent a small auger for the maximum time?

Answer 1

Stratton

This is a question about a linear function of the form y = mx + c.

Here y will be the total cost.

x will be the number of hours.

We are interested in finding y when x=22 (maximum time).

Next we need to find m,c.

c is the fixed cost so here it will be $ 39

m is the cost per hour, so here $ 15

So y = 15x + 39

And when x = 22, y = 15.22 + 39 = $ 369
