In July 2020, the price of electricity was
$0.27 per kilowatt-hour. The price of
electricity has increased at a rate of
approximately 2.5% annually. If t is the
number of years after 2020, create the
equation that can be used to determine how
many years it will take for the price per
kilowatt-hour to reach $0.54.
Write an equation in the form c = a[b]^t,
replacing the a, b, and c with their
appropriate values.
