Answer: Both intrinsic and extrinsic reward
Explanation:
Intrinsic motivation is when we do things simply because we find it enjoyable and we don't need any external reward for it. Since, Hana greatly enjoys the process of baking, especially the feelings of relaxation and creativity, this is an intrinsic reward.
On the other hand, extrinsic motivation occurs when one expects an external reward. Since, Hana feels very pleased when customers purchase her pies, and she makes enough money to pay her bills and save a little each month, she's extrinsically motivated.
Therefore, the answer is Both intrinsic and extrinsic reward.
