Mariah went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 250 mg of sodium and each frozen dinner has 450 mg of sodium. Mariah purchased twice as many frozen dinners as cans of soup and they all collectively contain 7200 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.
