I'm not sure how i'm supposed to set up the equation to solve this.

A phone company offers a plan for long distance service charges of .08 per minute. Another phone company offers a plan for $6 per month plus .02 per minute. For what number of minutes per month are the costs of the two plans the same?

just set up two expressions for the costs, and set them equal. For m minutes, you want

.08m = 6.00 + .02m

Now just find m which makes the two values equal.

To set up an equation to solve this problem, we need to equate the costs of the two plans.

Let's assume the number of minutes per month is represented by 'x'.

For the first phone company's plan (Plan A), the cost is given as $0.08 per minute. Therefore, the total cost for Plan A can be expressed as 0.08x.

For the second phone company's plan (Plan B), the cost is given as $6 per month plus $0.02 per minute. This can be expressed as 6 + 0.02x.

To find the number of minutes per month at which the costs are equal, we can set up the equation:

0.08x = 6 + 0.02x

Now, we can solve this equation to find the value of 'x'.

First, let's simplify the equation:

0.08x - 0.02x = 6

Combining the like terms, we get:

0.06x = 6

Divide both sides of the equation by 0.06 to isolate 'x':

x = 6 / 0.06

Now we can calculate the value of 'x':

x = 100

Therefore, the cost of the two plans will be the same when the number of minutes per month is 100.
