1.) In the sales campaign for a certain product, a full-page advertisement is run a total of
three times in three magazines A, B, and C. When the effects expected from running
a full-page advertisement zero to three times in each of the magazines are as shown in
the table below, how many times should the advertisement be run in magazine A to

individual magazines are independent of one another, and the effects from multiple
magazines can be calculated by simply adding the individual effects.
