You are trying to decide between two cell phone plans. Verizon offers a plan for $30 per month plus $0.03 per text message. AT&T has a plan that costs $10 per month plus $0.05 per text message. What is the “critical point” (number of texts) that will help you to determine the better plan for you?

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

this linear equation would have just one solution.

step-by-step explanation:

the reason why this would have one solution is that it is an expression with just one variable. since that variable is not raised to a power, it will always have just one solution.

17

step-by-step explanation:

51/3=17

thus 17 is your answer.
