Madison purchased 5 cans of soup and 7 frozen dinners.
Step-by-step explanation:
Given,
Quantity of sodium in each soup can = 500 mg
Quantity of sodium in each frozen dinner = 700 mg
Total quantity = 7400
Let,
Number of soup cans purchased = x
Number of frozen dinners purchased = y
According to given statement;
500x+700y=7400 Eqn 1
