6B. 85%, $17

Step-by-step explanation:

:) I think these are correct! They are in order from each page!

5A: 80*20%=16

6A: 84*50%=42

8: 80*75%=60

12: 130*40%=52

17: The printer costs $160, and 800*20%=160

2: 25% of 84 is 21 so there is 63 cm left. Divide by 6 and you get 10.5

3: 25% of 136 is 34 so he has 136-34 left, or 102

4: 17.5% of 240 is 42 so there are 198 other colors. Divide by 6 you get 33

5B: 42% of 132 is 55.44 if you subtract you get 76.56

6B: 100%-15%=85% and 85% of 20 is 17
