Part A: Marven has a coupon that discounts the rental of a full-sized car by $11 per day. They decide to buy insurance. If the cost is $505, how many days, d, will they rent the car? Write an equation.
Part B: Solve your equation from part A. How many days, d, did they rent the car.
Part C: They rent a car with insurance for 5 days but lost their coupon. If Marven AND the three friends spend $92.50 EACH, explain how you would determine which car they rented.

i hope this is what you were looking for.

see attached graph

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

hope this !

#12 the answer is the third option
