Answer:
Step-by-step explanation:
A cell phone provider offers a plan that costs $30 per month plus $0.10 per text message sent or received.
A comparable plan costs $50 per month but offers unlimited text messaging.
Let the number of massages be x
the total amount costs for plan A = $30 + $0.10x
We will calculate the number of messages at which both the companies charge equal amount.
30 + 0.10x = 50
0.10x = 50 - 30
0.10x = 20
x = [tex]\frac{20}{0.10}[/tex]
x = 200
At 200 massages both plan would charge equal.
Below 200 massages plan A will charge less but over 200 messages plan B would be better option.
