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. *

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

Therefore, the required equation is .

y = 2x

step-by-step explanation:

if you divide each number in the sequence, you'll see that they all have a multiple factor of 2. each number in the series, and any other numbers which may continue, will be multiplied by 2. therefore, y is the next number in the sequence, and x is the current one, so, our formula will be y = 2x.
