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
