nicole rented the bike for 26.6 minutes. 43=15+57(x) now because 57 is the hourly rate it needs to be divided by the number of minutes in one hour (60). 57/60=0.95cents now put that aside for later use, the next step in the equation is to subtract the one time fee of $15 from the total spent. $28 is what is left, now it's time to take that 0.95 and put it to use! 28*0.95=26.6 to double check that the math is correct take the 15+28 and make sure it adds up to 43
