Bill is trying to plan a meal to meet specific nutritional goals. he wants to prepare a meal containing rice, tofu, and peanuts that will provide 350 grams of carbohydrates, 311 grams of fat, and 168 grams of protein. he knows that each cup of rice provides 42 grams of carbohydrates, 0 grams of fat, and 1 grams of protein. each cup of tofu provides 4 grams of carbohydrates, 11 grams of fat, and 23 grams of protein. finally, each cup of peanuts provides 34 grams of carbohydrates, 75 grams of fat, and 35 grams of protein. how many cups of rice, tofu, and peanuts should he eat?

Bill needs to eat 5 Cups of rise, 1 cup of tofu and 4 cups of peanuts

Explanation:

Its simple calculations:

As  Bill requirement is 350 grams of carbohydrates, 311 grams of Fats and 168 gram of proteins.

Each cup of rice provides 42 grams of carbohydrates, 0 grams of fat, and 1 gram of protein.

Each cup of tofu provides 4 grams of carbohydrates, 11 grams of fat, and 23 grams of protein.

Each cup of peanuts provides 34 grams of carbohydrates, 75 grams of fat, and 35 grams of protein.

If he eats 5 cups of rise than he gets 42 × 5 = 210 grams of carbohydrates. similarly he gets 0 × 5 = 0 grams of fats and 1 × 5 = 5 grams of proteins.

If he eats 1 cup of tofu than he gets 4 × 1 = 4 grams of carbohydrates. similarly he gets 11 × 1 = 11 grams of fats and 23 × 1 = 23 grams of proteins.

and If he eats 4 cups of peanuts than he gets 34 × 4 = 136 grams of carbohydrates. Similarly he gets 75 × 4 = 300 grams of fats and 35 × 4 = 140 grams of proteins.

GRAND TOTAL BECOMES

CARBOHYDRATES: 210+4+136=350 grams

FATS: 0+11+300= 311 grams

PROTEINS:5+23+140=168 grams

the answer would be d
