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

[tex]y=500+50x[/tex]

Therefore, the required equation is [tex]y=500+50x[/tex].
