On Tuesday, she brings in 1 + 1 = 2 muffins. On Wednesday, she brings in 2 + 1 = 3 muffins. On Thursday, she brings in 3 + 1 = 4 muffins. On Friday, she brings in 4 + 1 = 5 muffins. In total, she brought 1 + 2 + 3 + 4 + 5 = 15 muffins to school to share with her friends. She baked a total of 15 + 7 = 22 muffins.

Reverse engineering the question: Amy bakes muffins for her friends. On Monday, she brings 1 muffin to school to share. Each day for the rest of the week she brings one more muffin to school than she did the day before. If on Saturday she counts that there are 7 muffins left, how many did she originally bake?
Reasoning and answer: If Lizette's average on the 3 quizzes is 94, then the sum of her scores in the 3 quizzes is 94 x 3 = 282. This means that the sum of her scores in the first 2 quizzes is 282 - 92 = 190. Thus, her average for the first 2 quizzes is 190 / 2 = 95.
The answer: 95
