<span>1. Write a system of equations to model the situation using c for cost and t for number of texts. </span>- 20+0.03t = 5+0.07t <span> 2. How many texts does a person need to send in a month to make the costs from both companies equal?</span> - two
So our equation would be 0.03x + 20 = 0.07x + 5, since we're trying to find the equal number of texts.
First, subtract the lesser x value, 0.03 on both sides so then the equation would be 20 = 0.04x + 5
Subtract 5 from both sides and you get 16 = 0.04x.
In order to get x by itself, we have to dived 0.04 on both sides and that leaves us with x = 500, which means that it would take 500 texts to make the companies equal
