First find the percentage of students who didn't like reading mystery stories.(100-85=15)
If 15% =30students
85%=?
85/15*30=170
Therefore 170 students liked reading mystery stories
<u>Equation/Question:</u>
Sarah began the week with $2.60 in her lunch account. She deposited $20 on Monday, and then spent $4.75 each day that week for lunch. What was the balance in her lunch account at the end of the day on Friday?
<u>Answer/Way I did it:</u>
2.60+20.00 = 22.6
4.75 * 5 = 23.75 (There's obviously 5 school days)
22.60 - 23.75 = 1.15

Answer:
subtract 10x from both sides
5x + 4 = 10x + 6
-10x -10x
subtract 4 from both sides
-5x + 4 = 6
<u> -4 -4</u>
-5x = 2
divide -5 from both sides
x = -2/5
