The two equations that would be needed to find out how many 1/2 pound servings Mariana can make are A and D:
A. 5 1/8 + 4 7/8 + 6 = 16
D. 16 ÷ 1/2 = 32Equation A adds up the total weight of the pasta, sauce, and onions to find the total weight of the pot of pasta. Equation D divides the total weight by 1/2 pound to find the number of 1/2 pound servings that can be made.Using equation A, we get 16 pounds of pasta mixture in total. Dividing this by 1/2 pound per serving using equation D, we get 32 servings in total.Therefore, Mariana can make 32 servings of 1/2 pound each from her pot of pasta
