when solved, we get
x = 17
Answer:
Step-by-step explanation:
I don't know if we are supposed to use the numbers from the previous problem. If not, then what ever number you choose will be 7 times the size of the protein. So let's assume that the givens follow question 2.
The amount of protein = x
The amount of carbs = (700/100)*x
proteins + carbs = 100%
x + 7x = 100 Combine the left
8x = 100 Divide by 8
8x/8 = 100/8
x = 12.5
Protein = 12.5 carbs
Carbs = 7*12.5 = 87.5 grams
So both cereals contain 12.5 grams of proteins and 87.5 grams of carbs.
