Melissa's brother is playing in a basketball tournament at the local community center. Each family is expected to have someone helping in some way at the center. Her mom volunteers Melissa to help at the concession stand so her parents can watch her brother play. Melissa wants to go to a sleepover at her friend's house the night before but knows she will not get any sleep if she does and will therefore be cranky during the tournament. She tells her friend she cannot come to the sleepover and instead goes to the community center on Saturday morning to help at the concession stand. What type of motivation is Melissa showing? (extrinsic motivation)
(intrinsic motivation)
(memory motivation)
(no motivation)

Intristic motivation

Explanation:

Extristic motivation would be like being forced to do something. She could have easily gone to the sleepover and still been physically able to go to work on the concession stand and was not told not to go by, say, her mother, but she chose not to go anyways because of the fact that she didn't want to be "cranky" the next day.

No motivation was NOT shown because she did something she didn't want to do to make something that she was going to do in the future a lot less difficult.

Memory motivation, I'm assuming by the name is NOT the answer either because the textual evidence didn't show any proof that she had done this before when I read it.

So it must be intristic motivation, because she did something she didn't want to do to make something that she was going to do in the future a lot less difficult.
