C= the price of a cheeseburger and l = the price of a lemonade:

Divide the second equation by -2 to begin the process of solving by elimination:

Now that we have c, 4, we can plug it in to one of the equations to find l:

So, each cheeseburger is $4 and each lemonade is $1. The final answer is:
1 cheeseburger and 2 cups of lemonade would cost $6.
1 cup = 8 fluid ounces.
6.875 cups = ? fluid ounces.
8*6.875=55.
Your answer would be 55 fluid ounces.
