If a certain brand of icecream is 99% fat free, how many cups would you have to eat to ingest the same amount of fat that would

sdas [7]

Answer:

10,000 cups

Step-by-step explanation:

Direct proportional quantities are such that their quotients are always the same number. Example: If I need one cup of sugar to prepare 5 candies, I will need 2 cups of sugar to prepare 10 candies. The quotient 5/1 is equal to the quotient 10/2

Let's suppose a cup of regular ice cream would have 100 parts of fat.

The brand of ice cream mentioned in the question is 99% fat-free which means for every cup of their ice cream, we'll only get 1 part of fat. The relation is 100/1.

If we wanted 100 parts of fat out of fat-free ice cream we would need 100*100/1=10,000 cups of it

These numbers won't change if we used another number instead of 100 in the example shown.

359 rounded to nearest 100 = 400

309 rounded to nearest 100 = 300

800 + 400 + 300 = $1,500 estimated total cost
