Chef Selena is making her special dish that requires pasta, sauce, and onions. She has 5 1/8 pounds of pasta, 6 pounds of sauce,
arlik [135]

Answer:

\text{Total Weight of Food Made}, x=5\frac{1}{8}+6+4\frac{7}{8}\\\text{Number of Servings}, y=x \div \frac{1}{2}

Step-by-step explanation:

The Weight of Ingredients to be used by Chef Selena are:

  • 5\frac{1}{8} pounds of pasta,
  • 6 pounds of sauce; and
  • 4\frac{7}{8} pounds of onions.

Total Weight of Food Made, x

=5\frac{1}{8}+6+4\frac{7}{8}\\=5+6+4+\frac{1}{8}+\frac{7}{8}\\=16 \: Pounds

Since each serving is \frac{1}{2} Pounds

Number of Servings of her dish, y

16 \div \frac{1}{2}\\ =32 \: Servings

The two equations needed to solve the problem are therefore:

\text{Total Weight of Food Made}, x=5\frac{1}{8}+6+4\frac{7}{8}\\\text{Number of Servings}, y=x \div \frac{1}{2}
