unt, got 23,000 responses. If you mail to the same size list and offer a discount, how many responses would you expect? a) 41,400 b) 44,000 c) 48,300 d) 52,400
For this case we can make the following rule of three: 23000 -------> 100% x --------------> 180% Clearing the value of x we have: x = (180/100) * (23000) x = 41400 Answer: you would expect about: a) 41,400 responses
