We can work this out by looking for the total of people that like tennis in the table, and subtracting it from the total amount of people that like baseball.
This gives us a total of 46 people that like baseball, subtract 40 people that like tennis, and 46 - 40 = 6.

Since c=15 and d=3, we replace the c and d variables with 15 and 3.
0.5x15-1.7x3
0.5x15=7.5
1.7x3=5.1
Now subtract.
7.5-5.1=2.4
