At a sporting event, the price for 3 cheeseburgers and 2 cups of lemonade is $14 and the price for 2 cheeseburgers and 4 cups of
crimeas [40]
C= the price of a cheeseburger and l = the price of a lemonade:

3c + 2l=14\\2c+4l=12

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

3c + 2l=14\\-1/2\ (2c+4l=12)\\\\3c+2l=14\\-c-2l=-6\\\\2c=8\\c=4

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

3c + 2l=14\\3(4)+2l=14\\12+2l=14\\2l=2\\l=1

So, each cheeseburger is $4 and each lemonade is $1.  The final answer is:

1 cheeseburger and 2 cups of lemonade would cost $6.

1/2 gram + 3/4 gram = 1 1/4 total grams


Divide the total grams by 1/8 to find the number of experiments they can do:

1 1/4 / 1/8 = 5/4 / 1/8 = 5/4 * 8/1 = 40/4 = 10


They can conduct 10 experiments.
