For a certain year, the combined revenues for pepsico and coca-cila were $51 billion. if the revenue for pepsico was $9billiin more than coca-cola, how much was the revenue of each company? found to the nearest billion, if necessary.

So if the combined revenues were $51 billion. Then it would be best to divide that between the two companies as a starting point. Each company would have $25.5 billion if they were split 50-50. Since PepsiCo has 9 billion more than Coca-Cola. Simply take PepsiCo's value and add $9 billion to it, which would be $34.5 billion. Finally, take $51 billion, subtract it $34.5 billion, which is PepsiCo's value to get Coca-Cola's value, which is 16.5 billion for me.

Let us say the revenue of coca cola was x then the revenue for PepsiCo isx+9
x + x+9 = 51
2x = 51-9
2x = 42
x=21
Therefore the revenue of coca cola I.e x = $21
And the revenue of pepsico I.e x+9 =21 + 9 =$30

Where’s the problems ? ?
