Madison went to the grocery store and purchased cans of soup and frozen dinners. Each can of soup has 500 mg of sodium and each frozen dinner has 700 mg of sodium. Madison purchased 2 more frozen dinners than cans of soup and they all collectively contain 7400 mg of sodium. Determine the number of cans of soup purchased and the number of frozen dinners purchased.

x = soup cans      sodium = 500x

x+2 = dinners       sodium = 700(x+2)     summed = 7400

 

500x + 700(x+2)   = 7400      solve for x = #cans of soup    then   dinners = x+2
