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.

At the 4 month, the cost will be the same

Step-by-step explanation:

suppose x is the number of month.

Plan A= 40+20x

Plan B= 30x

40/10=x

4=x

At the 4 month, the cost will be the same.
