Divide the amount saved by the original price then multiply by 100 to get the percent:
6/40 = 0.15
0.15 x 100 = 15%
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.
