robert went to the grocery store and purchased cans of soup and frozen dinners. each can of soup has 300 mg of sodium and each frozen dinner has 500 mg of sodium. robert purchased a total of 14 cans of soup and frozen dinners which collectively contain 5200 mg of sodium. write a system of equations that could be used to determine the number of cans of soup purchased and the number of frozen dinners purchased. define the variables that you use to write the system.

Let s stand for soup, and f stand for frozen dinners.

s + f = 14

s(300mg) + f(500mg) = 5200mg

Step-by-step explanation:

He bought 14 frozen dinners and soups all together, so whatever number you plug in for soups and frozen dinners has to equal 14. Then, you have to make the equations also equal 5200mg. So whatever you plug in for the first equation needs to also work for the second.
