a cell phone provider offers a plan that costs $30 per month plus $.20 per text message sent or received. A comparable plan cost $50 per month but offers unlimited text messaging.  How many text messages would have to be sent or received in order for the plans to cost the same each​ month?

Respuesta :

One text message sent or recieved
$50 per month
$30 per month
50 - 30 = 20
It is 20$ per text in the first plan there for one text either sent or recieven would make the first plan 50$ making the plans equal in cost
30+0.20x=50
0.20x=20
x= 100 texts
