Hello i hope you having a good day :) Question : Part a: Abe rented a bike at $36 for five days. If he rents the same bike for eight days, he has to pay a total rent of $48.
So we can set the fixed free of the renting that would be (f) and the dynamic free as (d) per the day then we have F + 5d = 36 F + 8d = 48 there for we have f = 16 and d = 4 so it would be y = 16 + 4x.
Hopefully this help you.
