HELP ME PLZ! :3
It cost $83 a day to rent a car plus a required fee for insurance. Suppose the total cost for renting a car for 7 day is $621.
Part A: Write an equation to model this situation.
(Write the equation in slope-intercept form)
Part B: How much does the insurance cost?

Respuesta :

Part A:
y=mx+b
621=83(7)+b

Part B:
621=83(7)+b
621=581+b
621-581=b
b=40
Insurance cost is 40$
