Answer:
the answer is below :)
Step-by-step explanation:
BigBytes will be 100 +10x = y ($100 flat fee plus 10 times the number of gigabytes equals total cost).
GoGig will be 120 + 5x = y. ($120 flat fee plus 5 times the number of gigabytes equals total cost).
Now set them equal to each other and solve for x to find where the gigabytes are the same.
100 + 10x = 120 + 5x
Subtract 100 from both sides: 10x = 20 + 5x
Subtract 5x from both sides: 5x = 20.
Divide both sides by 5: x = 4. 4 gigabytes is the answer.
