Marta likes to make soup during the winter months. No matter how much soup she makes, she always freezes 32 ounces to save for later, then serves what's left.

Write an expression to show the amount of soup Marta has left. Let "s" equal the number of ounces of soup Marta makes.

Symbols you can use:

+ / - / x / ➗ / ( / ) / s / 32

Final answer:

The expression for the amount of soup Marta has left after freezing 32 ounces is s - 32. Devon will need to make 37.5 liters of soup for 100 guests. When converting units like quarts to ounces, multiplying or dividing depends on whether you're going from a larger to smaller unit or vice versa.

Step-by-step explanation:

To determine the amount of soup Marta has left after freezing 32 ounces, we use the expression s - 32, where 's' represents the total ounces of soup Marta makes. For Devon's situation, she needs to calculate the total amount of soup for 100 guests, with 375 milliliters per guest. This is calculated as 100 x 375 ml = 37500 ml, which is 37.5 liters, because 1000 milliliters equal 1 liter.

Marcy's scenario deals with having 1500 grams of meat and needing 900 grams for her recipe. She will have 600 grams of meat left after using the amount her recipe calls for.

When converting units, such as quarts to ounces or pints to ounces, consider whether you need to multiply or divide. Generally, you multiply when converting from a larger unit to a smaller unit, and divide for the opposite.
