A waiter is asked to increase his check average by "suggestively selling" appetizers, salads, and desserts. It has been explained to the waiter that the larger his check average, the more he will make in tips. However, the waiter does not believe that suggestive selling will actually result in increased tips. In this scenario, the waiter's belief that suggestive selling is not likely to result in more tips exemplifies:.
a. equity
b. expectancy
c. instrumentality
d. valence

c. instrumentality

Explanation:

Instrumentality refers to the Quality of being an instrument, Agency or means by which an entity accomplishes its functions or fulfills its obligations, achieves it purpose or gets to a conclusion.

The waiter believes that suggestive selling is not instrumental to the amount of tips she gets.

It can not be proven that by suggesting what a customer buys for him will automatically lead to him or her tipping you while leaving.

Suggestive selling implies trying to suggest to a customer what to buy from a store you own or you are working.
