Adietician works in a hospital and prepares meals under the guidance of a physician. suppose that for a particular patient, a physician prescribes a meal to have 550 calories, 35 g of protein, and 140 mg of vitamin c. the dietician decides to prepare the meal using steak (each 3-oz serving contains 300 cal, 20 g of protein, and no vitamin c), baked potatoes (one baked potato contains 100 cal, 5 g of protein, and 20 mg of vitamin c), and brussels sprouts (one 156-g serving contains 50 cal, 5 g of protein, and 100 mg of vitamin c). how many servings of each food are required to satisfy the physician's requirements?

The food servings required to satisfy the physician's requirements: one 3-oz serving of steak, one 156-g serving of Brussels sprouts and two baked potatoes.

Step-by-step explanation:

The patient needs a meal having 550 calories, 35 g of protein and 140 mg of vitamin C.

Total calorie required = 550   equation (1)

calories in one serving of steak = 300 equation (2)

calories in one baked potato = 100       equation (3)

calories in one serving of Brussels sprouts = 50 equation(4)

Total calories in one serving of each food = equation (2) + (3) + (4)

                                                                = 300 + 100 +50 = 450 equation(5)

The balance calorie required = equation (1) - (5)

                                                = 550 - 450 = 100   equation (6)

Total protein needed = 35 g       equation (7)

Protein in one serving of steak = 20 g equation (8)

Protein in one baked potato = 5 g       equation (9)

Protein in one serving of Brussels sprouts = 5 g equation(10)

Total protein in one serving of each food = equation (8) + (9) + (10)

                                                                     = 20 + 5 + 5 = 30 g equation(11)

The balance protein required = equation (7) - (11)

                                              = 35 - 30 = 5 g equation (12)

Total Vitamin C needed = 140 mg       equation (13)

Vitamin C in one serving of steak = 0 mg equation (14)

Vitamin C in one baked potato = 20 mg       equation (15)

Vitamin C in one serving of Brussels sprouts = 100 mg equation(16)

Total Vitamin C in one serving of each food = equation (14) + (15) + (16)

                                                              = 0 + 20 + 100 = 120 mg ... equation(17)

The balance Vitamin C required = equation (13) - (17)

                                                   = 140 - 120 = 20 mg   equation (18)

From equations (6), (12) and (18), the required calories, protein and vitamin C after one serving of each food items is 100 calories, 5 g of protein and 20 mg of vitamin C, which is the equivalent of one baked potato.

Hence, one 3-oz serving of steak, one 156-g serving of Brussels sprouts and two baked potatoes meets the physician's prescribed meal requirements.

the answer is d

the answer is in the first quadrant, which make the y-int positive.

since the dots are going down, therefore the correlation is negative

i hope it is right.
