When we look at ratios, we use for : against and add both to get the total in the set. therefore 8+3 = 11. divide the 22000 fans into 11 sections we have each section worth 2000 fans. The number of blue sox fans would be 3 x 2000 or 6000 fans with the remaining 16000 being baron fans.
If they sell the same amount next year and want to reach $1,500, they must higher the price. to do that, they can divide the $1500 by the number of agendas. Do the math yourself, its not very hard.
