a cell phone plan includes 450 anytime minutes for \$35 per month plus \$13.85 for a cell phone and \$25 for a activation fee. let x represent the number of months of service. write an equation in the form of y=mx+b. find the ordered pair associated with the equation x=5. if you sign a 1-yr contract, how much will this cell phone package cost?

You should think about how this works in real life. You have to start off by paying \$13.85 AND \$25 right off the bat. Then, you pay \$35 per month, so you would have to multiply the \$35 by the number of months you are getting service. So that means that the 35 gets multiplied by the x. The y-intercept would be the \$13.85 and the \$25 added together, which is \$38.85.

So, the equation would look like this: y = 35x + 38.85

To find the ordered pair associated with x=5, you need to plug in 5 for x:

y = 35x + 38.85

y = 35(5) + 38.85

y = 175 + 38.85

y = 213.85

The ordered pair would be (5, 213.85). What it means is that you would have paid \$213.85 total for 5 months of service.

If you want to know how much it costs for a 1 year contract, you need to think about how many months that is. It's 12 months. So that's what you plug in for x.

y = 35x + 38.85

y = 35(12) + 38.85

y = 420 + 38.85

y = 458.85

For a 1-year contract, the plan costs \$458.85.

I hope this helps you move forward on the problem! Let me know if you need any more clarification!
