Further explanation

Order of Operations in Mathematics follow this following rule :

1. Parentheses
2. Exponents
3. Multiplication and Division
4. Addition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem !

$\texttt{ }$

Melanie bought 3 sacks of potatoes. Each sack of potatoes weighed 4 pounds.

$\texttt{Total mass of 3 sacks of potatoes} = 3 \times 4 = 12 \texttt{ pounds}$

$\texttt{ }$

Melanie bought 2 sacks of tomatoes. Each sack of tomatoes weighed 2 pounds.

$\texttt{Total mass of 2 sacks of tomatoes} = 2 \times 2 = 4 \texttt{ pounds}$

$\texttt{ }$

Melanie bought a watermelon. Each watermelon weighed 22 pounds.

$\texttt{Total mass of a watermelon} = 1 \times 22 = 22 \texttt{ pounds}$

$\texttt{ }$

$\texttt{Total mass} = 12 + 4 + 22 = 38 \texttt{ pounds}$

Answer 2

How many pounds of produce did she buy? 38 pounds

Explanation:

A farmers' market is a physical retail marketplace to sell foods by farmers to consumers directly.

At the produce market, Melanie bought:

• 3 sacks of potatoes,
• 2 sacks of tomatoes,
• a watermelon.

Each sack of potatoes weighed 4 pounds, each sack of tomatoes weighed 2 pounds, and the watermelon weighed 22 pounds

In working on a mathematical problem, we first calculate operation that is in parentheses, then exponentiation, multiplication or division, finally addition or subtraction.

Melanie bought :

• 3 sacks of potatoes, Potatoes contain a good amount of carbs and fiber, as well as vitamin C, vitamin B6, potassium and manganese. Each sack of potatoes weighed 4 pounds
• 2 sacks of tomatoes that is a great source of vitamin C, potassium, folate, and vitamin K. Each sack of tomatoes weighed 2 pounds.
• a watermelon that include vitamins A, B6, C, magnesium and potassium. Each watermelon weighed 22 pounds.

Pound is unit of avoirdupois weight, and it is equal to 16 ounces, 7000 grains, or 0.45359237 kg,

Therefore total mass is;

For potato $3*4 pounds = 12 pounds$

For tomato $2*2 pounds = 4 pounds$

For watermelon $1*22 pounds = 22 pounds$

Total mass = $12 + 4 + 22 pounds = 38 pounds$

How many pounds of produce did she buy is 38 pounds
