I’M LOSING TIME!!!!!! you are trying to decide which cell phone plan to purchase. Plan A chargeres \$40 for a new phone and \$20 a month for usage. Plan B provides the phone for free, but has a fee of \$30 a month for usage.
Use the substitution method to determine when the two plans will cost the same.
