Customers of a phone company can choose between two service plans for long distance calls. The first plan has a \$17 one-time activation fee and charges 8 cents a minute. The second plan has no activation fee and charges 12 cents a minute. After how many minutes of long distance calls will the costs of the two plans be equal?

## To find the number of minutes after which the costs of the two plans will be equal, we can set up an equation using the given information.

Let's denote the number of minutes as "m".

For the first plan, the cost would be 17 + 0.08m (activation fee plus 8 cents per minute).
For the second plan, the cost would be 0 + 0.12m (no activation fee plus 12 cents per minute).

We can set up the following equation:

17 + 0.08m = 0 + 0.12m

Now, let's solve this equation to find the value of "m".

Subtracting 0.08m from both sides of the equation:

17 = 0.12m - 0.08m

Simplifying:

17 = 0.04m

Dividing both sides of the equation by 0.04:

17/0.04 = m

425 = m

Therefore, after 425 minutes of long distance calls, the costs of the two plans will be equal.
