David's phone bill each month is $30. He is also charged $0.10 per GB of data he uses. If his phone bill in July was $42, how many GB of data did he use in July?

Variable:

Equation:

Solution:

So. If his total bill was $42 lets subtract the 30 that comes out every month automatically, now we are just left with 12, if each GB costs 0.10 then all you would do to find out how many GB he used is do 12/0.10 (which is really just 12*10) which will get you 120

Meaning that he used 120 GB

(That's a lot!)
