Cholesterol should be limited to at most 300 mg per day. Fast food hamburgers have high amounts of cholesterol. Two McDonald’s Q
topjm [15]

Answer: 203.5mg and 322.5mg

Step-by-step explanation:

Let represent two serving of Mc Donald quarter pounds with = m

Let three Burger King whopper = b

given:

1). m + b = 300 + 395......equation 1.

1). m + b = 695.

And

2). 3m + b = 288.......... equation 2.

• Using Elimination method, Multiply both sides of eqn.(1) and (2)by 3. then

-3m + 3b = 2084

9m + 3b = 864

Subtract equation (1) from (2).

6m = 1221

Divide both sides by -6

m = 203.5

Substitute (m) into equation 1

3m + b = 288.

3(203.5) + b = 288.

610.5 + b = 288

b = 610.5 - 288

b = 322.5

Two servings of Mc Donald quarter pound has 203.5mg of cholesterol.

Three servings of whopper has 322.5mg of cholesterol.
