Question

Andy's phone plan charges $0.45 per text message plus a $20 monthly fee. Jeff's plan charges $0.20 a text plus an additional $35 monthly fee. Which equation can be used to determine when the phone plans will cost the same based on the number of texts?

Answer 1

20+0.45x=35+0.20x

Explanation:

From the information given, you can say that Andy's plan cost would be equal to Jeff's plan cost and then solve for the number of text to find when the phone plans will cost the same:

20+0.45x=35+0.20x, where x is the number of texts

Now, you can solve for x:

0.45x-0.20x=35-20

0.25x=15

x=15/0.25

x=60

According to this, the equation that can be used to determine when the phone plans will cost the same based on the number of texts is 20+0.45x=35+0.20x.
