Question

Lincoln 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. Lincoln purchased a total of 27 cans of soup and frozen dinners which collectively contain 11,500 mg of sodium.

Answer 1

Explanation:

If Madison purchased 2 more frozen dinners than cans of soup, then we have the equation

If each can of soup has 500 mg, each dinner is 700 mg, and she bought 7400 mg of sodium total, we can come up with the equation

Replacing the d in with s + 2, we get the equation

Using the distributive formula, we get

Simplifying this equation gives

6000/1200 = 5

so s = 5

if d = s + 2, d must equal 7

So Madison ordered 5 cans of soup and 7 frozen dinners.
