Cell phone company a charges $20 each month plus $0.03 per text. cell phone company b charges $5 each month plus $0.07 per text. write a system of equations to model the situation using c for cost and t for number of texts. how many texts does a person need to send in a month to make the costs from both companies equal?

The cost from company A

And  the cost from company B

The number of a person need to send in a month to make the costs from both companies equal=3,750

Step-by-step explanation:

Let 't' be the number of text in a month.

Therefore, the cost from company A

And  the cost from company B

To find the number of text a person need to send in a month such that the costs from both companies equal, we need to equate the above functions.

Hence, the number of a person need to send in a month to make the costs from both companies equal=3,750

in simplified version   it would be x ≤-4

step-by-step explanation:

multiply each term in x ≤-4 by -1

this is answer of 144 cubic meters
