Final answer:
DiGiorno's sales were 1014.6 million dollars and Red Baron's sales were 572.3 million dollars.
Step-by-step explanation:
Let's assume DiGiorno's sales in millions as x million dollars. According to the information given, Red Baron's sales were $442.3 million less than DiGiorno's. So Red Baron's sales in millions can be represented as x - 442.3 million dollars.
We are also given that the top-selling frozen pizza brands, DiGiorno and Red Baron, together had sales of $1586.9 million. So, we can write an equation to represent this: x + (x - 442.3) = 1586.9 million dollars.
Simplifying the equation gives us: 2x - 442.3 = 1586.9.
Now, let's solve for x: 2x = 1586.9 + 442.3 => 2x = 2029.2 => x = 1014.6 million dollars.
Therefore, DiGiorno's sales were 1014.6 million dollars and Red Baron's sales were 1014.6 - 442.3 = 572.3 million dollars.
