Please help me. I am having some trouble on this problem.

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.
