Help me with my math please!?

Question

The grocery store has bulk pecans on sale, which is great since you're planning on making 8 pecan pies for a wedding. How many pounds of pecans should you buy?

Serving size: 1 cup 99g. servings per container: about 2

How many pecans are needed for each pie? Your recipe calls for 1 3/4 cups pecans per pie. But there is no cup measure available, only a scale.

how many pounds of pecans will you need to buy?

Answer 1

1 cup = 99g. Let's round that to 100g

1.75 * 100g = 175g per pie (since each pie uses 1.75 cups)

175 * 8 = 1400g in total (since you're making 8 pies)

453.6 grams ≈ 1 pound Let's round that to 450

1400 / 450 grams ≈ 3.1111....

Round that off to 3 pounds of pecans needed

If you'd rather have more precise, then here:

1.75 * 99g * 8 = 1386 grams of pecans needed for the pies

1386 / 453.6 ≈ 3.05555.... pounds
