The values of a, b, and c from the table are 34, 18, and 68 respectively.
From the given table, the following equations are true;
- number of subscribers above $25000 + number of those not subscribing above $25000 = 47
Set theory
Substituting the values:
a + 13 = 47
a = 47 - 13
a = 34
Similarly;
b + 55 = 73
b = 73 - 55
b = 18
Also, c = 13 + 55
c = 68
Hence the values of a, b, and c from the table are 34, 18, and 68 respectively.
