the cost per data would be 10 dollors

Answer: Cost per gb of data = y = $5.

Step-by-step explanation:

Let the initial fee be 'x'.

Let the fees depending on the amount of data he use be 'y'.

After using 3 GB of data , he owes $30.

After using 5 GB of data , he owes $40.

According to question, our equations would be

[tex]x+3y=\$30--------(1)\\\\x+5y=\$40------(2)[/tex]

So, Using elimination method , we get that

[tex]x+3y=\$30\\\\x+5y=\$40\\\\----------------------------------------\\\\-2y=-10\\\\y=\dfrac{10}{2}\\\\y=\$5[/tex]

Hence, Cost per gb of data = y = $5.
