Cell phone Plan B costs $50 per month but does not come with a phone. If you choose this plan, you will need to purchase a phone for $500. Let x = the number of months and y = the total cost of the cell phone plan. Write an equation to represent the cost of Cell phone Plan B. *

Answer 1

Given:

Cell phone Plan B costs $50 per month.

Cost of phone = $500

To find:

An equation to represent the cost of Cell phone Plan B. *

Solution:

We have,

Cost of phone = $500

Cost of cell phone Plan B for one month = $50

Let x be the number of months and y be the total cost of the cell phone plan.

Cost of cell phone Plan B for x months = $50x

Now,

Total cost of Cell phone Plan B = Cost of phone + Cost of cell phone Plan B for x months

`y=500+50x`

Therefore, the required equation is
`y=500+50x`.
