15. oscar wants to rent a boat. the rental shop charges and initial fee of $12 plus $8 per hour to rent the boat. write a equation to find c, the total cost of renting a boat, for h hours.

C=8h+12
the 8h represents the $8 per hour for renting the boat, and h represents however many hours you rent the boat for.  The +12 is the initial $12 fee.  This is in slope intercept form, just using different variables than y=mx+b
