Alrighty, so you said, simplify: 4t (2s - 7)
When there is a variable or number outside of the parenthesis, it means that it wants the whole thing multiplied by that number.
So, your right way to do this is:
4t (2s) + 4t (-7)
Simplify.
8st - 28t
So, the student incorrectly simplified them because she didn't multiply -7 by 4t like they should have.

Step-by-step explanation:
In 1 hour, Hannah will play 6 2/5 songs, or 32/5.
To get from 5/8 to 1, you have to multiply by the number 1 3/5 (5/8 • 1 3/5 = 1). So, you multiply 4 by 1 3/5 too. (4 • 1 3/5) This gets you to the final answer, 6 2/5.
