(50+40x) dollars

Step-by-step explanation:

THe fixed cost is $50 (this includes everything and 6GB of data).

Now, for every GB OVER 6 GB he uses, company charges $40 extra.

So, if he used "x" GB EXTRA, his EXTRA cost will be 40 * x = 40x

Thus, his total cost in the month would be fixed cost PLUS the extra, which would be

50 + 40x dollars
