A certain cellular phone plan charges $41.00​ per month plus $0.1​ for each minute of usage. The monthly charge is given by the formula monthly charge =0.1x+41 where x represents the number of minutes of usage per month. What is the charge for a month with 270​ minutes of usage? Write your answer to two decimal places as money is traditionally written.

Respuesta :

=0.1(270)+41

(270*0.1; move one decimal to the right, then being 27.0)
=27+41=68

Hope this helps!
