Question

You’re trying to decide which cell phone plan to purchase. Plan A charges $40 for a new phone and $20 a month for usage. Plan B provides the phone for free, but has a fee of $30 s month for usage. Write an equation to represent each plan

Answer 1

Answer:

Plan A - 20x+40

Plan B - 30x

Step-by-step explanation:

x will determine the number of months.

For example, Plan A's equation

If I paid for one month, I should get $60.

20(1)+40 = 60

Now for three months, I should get $100. Because Plan A charges $20/month after a one time fee of $40 for the new phone.

20(3)+40 = 100

On the other hand, Plan B gives away a free phone, meaning no one-time fees. It only charges us $30/month. That's easy.

30(1) = $30

30(3) = $90
