Given that Nicole rented a bike from Krystal's Bikes, the number of hours is
4 hours
Given data
Initial Cost = $15
Cost per extra hours = $7
Amount Paid = $43
The Expression that we will use to describe this situation is modelled below
let y = Amount paid
m = cost per extra hour
x = the number of hours
c = the initial cost
y = mx + c -------- Equation of line
43 = 7*x + 15
43 = 7x+15
7x = 43-15
7x = 28
divide both sides by 7
x= 28/7
x= 4 hours
Hence the number of hours is 4 hours
