Three new data storage companies are competing for your business. Their cost per Gigabyte (GB) of storage is shown in the table for a year's worth of service. Use this information to answer all of the questions for the lesson.
2

If you plan on storing 100g of data, which company would you go with? Type a response into the show your work area of why you made your selection.

3

How much does each company charge per gig? (Slope)

3

What companies have a sign up fee? (find the y-intercept for each company using the slope that was calculated in the last problem)

2

Write an equation for CloudSpace (put together the rate and the y-intercept). y=mx+b

2

Write an equation for DocuSpace (put together the rate and the y-intercept). y=mx+b

2

Write an equation for AirDriver (put together the rate and the y-intercept). y=mx+b

2

At what point are all three companies the same cost?

2

If you plan on storing 250g of data, which company would you go with? Type a response into the show your work area of why you made your selection.
