Alan Le · Answer 1

x + y = 14 and 300x + 500y = 5200

Step-by-step explanation:

Let us assume that Robert purchased x number of cans of shop which had 300 mg of sodium each and y number of cans of frozen dinners which contained 500 mg of sodium each.

If Robert purchased a total of 14 cans which collectively contained 5200 mg of sodium, then we can write two equations using x and y. They are

x + y = 14 ... (1) and

300x + 500y = 5200 ... (2).

Therefore, equations (1) and (2) are the required system of equations which can be solved to get the values of x and y. (Answer)
