Answer:
The point of intersection is the number of gigabytes and the total cost when the two plans cost the same.
Step-by-step explanation:
Company A doesn't charge a fee "per gigabyte", there's just a flat fee and it is $100. Company B only charges a flat fee of $20, BUT there IS a "per gigabyte" charge. These two plans actually cost exactly the same when the customer uses 16 gigabytes.
