Best ResponseYou've already chosen the best response.23001209030 = 60 80 people play both sports its arithematic, not algebra we start with 300 people, 120 play onlyhockey meaning 180 people play basketball or dont play a sport, or both sports 30 people dont play a sport meaning 150 people play basketball or both sports 90 people play only basketball leaving only 60 people that play both sports

Best ResponseYou've already chosen the best response.2if you wanted to find the total amount of people who play basket ball, take the amount of people who play only basketball, and then add it to the number of people who play both sports same for hockey
