Question

An international data plan charges $10.00 for 4GB of data. Anything over 4GB is priced at $2.50 per GB. Which equation can be used to find y, the total cost of the international plan, if x represents the number of GB over 4?

y = 2.50x + 10


y = 2.50x


x = 10x + 2.50

Answer 1

Step-by-step explanation:

Let the total cost of international plan = y

x be the cost of plan for over 4 GB.

Fixed charge for 4 GB = $10

Now y = 2.50x + 10
