Giving the following information:

Present value= $3.7

Future value= $4.8

Growth rate= 5%

To calculate the time required to reach  $4.8, we need to use the following formula:

n= ln(FV/PV) / ln(1+g)

n= ln(4.8 / 3.7) / ln(1.05)

n= 5.33

It will take 5.33 years for the price of gas to reach $4.8.-
