1. calories in food:_________________

carbs: 6 grams
protein: 8 grams
fat: 4 grams

1. calories in food:_________________

carbs: 2 grams
protein: 9 grams
fat: 9 grams

1. calories in food:_________________

carbs: 1 gram
protein: 3 grams
fat: 13 grams

1. calories in food:_________________

carbs: 5 grams
protein: 6 grams
fat: 7 grams

Explanation:

Step1: Calculate calories from carbs, protein and fat for each food.

For problem 1:
Calories from carbs: \(4\times4 = 16\)
Calories from protein: \(4\times7=28\)
Calories from fat: \(9\times3 = 27\)
Total calories: \(16 + 28+27=71\)

For problem 2:
Calories from carbs: \(4\times6 = 24\)
Calories from protein: \(4\times8 = 32\)
Calories from fat: \(9\times4=36\)
Total calories: \(24+32 + 36=92\)

For problem 3:
Calories from carbs: \(4\times2=8\)
Calories from protein: \(4\times9 = 36\)
Calories from fat: \(9\times9=81\)
Total calories: \(8+36 + 81=125\)

For problem 4:
Calories from carbs: \(4\times1=4\)
Calories from protein: \(4\times3=12\)
Calories from fat: \(9\times13 = 117\)
Total calories: \(4+12+117 = 133\)

For problem 5:
Calories from carbs: \(4\times5=20\)
Calories from protein: \(4\times6=24\)
Calories from fat: \(9\times7=63\)
Total calories: \(20+24 + 63=107\)

Answer:

1. \(71\)
2. \(92\)
3. \(125\)
4. \(133\)
5. \(107\)
