Give the step-by-step reasoning process and then the final answer. The Franzia wine is three times as old as the Carlo Rosi, while the Carlo Rosi is four times older than the Twin Valley. Calculate the total age of the three brands of wine if the Carlo Rosi is 40 years old.
If the Franzia wine brand is three times as old as the Carlo Rosi, then the Carlo Rosi is 3 * 40 = 120 years old. The total number of years the Carlo Rosi and the Franzia wine brands have been around is 120 + 40 = 160 years. The Carlo Rosi is four times older than the Twin Valley wine brand, meaning the Twin valley wine brand is 40 / 4 = 10 years old. Together, the three bands have a total of 10 + 160 = 170 years of existence.
The final answer: 170.
