Your friend invites you to go inline skating at Munson state park. you'd like to go but since you don't have skates or a helmet
you'll have to rent them. You'll also have to pay for a park permit. Write a formula that will help you determine your total cost. lets let helmet rental=h
skate rental=s
park permit=d
total cost=c
It's basically a spinoff of the y=mx+b formula except there are two x's in case you don't know exactly how many to buy or else you'd literally just add them all together. I hope this helps and gives you a better idea on how to solve it.
