Answer:

9.) t=.05m+20

10.) t=.10m+5

11.) 300 minutes of calling would make the two plans equal.

12.) Company B.

Step-by-step explanation:

Let <em>t</em> equal the total cost, and <em>m,</em> minutes.

Set up your models for questions 9 & 10 like this:

<em>total cost = (cost per minute)# of minutes + monthly fee</em>

Substitute your values for #9:

t=.05m+20

Substitute your values for #10:

t=.10m+5

__

To find how many minutes of calling would result in an equal total cost, we have to set the two models we just got equal to each other.

.10m+5=.05m+20

Let's subtract 5 from both sides of the equation:

.10m=.05m-15

Subtract .05m from both sides of the equation:

.05m=15

Divide by the coefficient of m, in this case: .05

m=300

__

Let's substitute 200 minutes into both of our original models from questions 9 & 10 to see which one the person should choose (the cheaper one).

Company A:

t=.05(200)+20

Multiply.

t=10+20

Add.

t=30

Company B:

t=.10(200)+5

Multiply.

t=20+5

Add.

t=25
