Answer:

Step-by-step explanation:
the girl is selling tickets for dollars 15 and she wants to raise more than dollars 180. that means we need a symbol that will make it so that $180 is always less than. like such.

Answer:
40%
Step-by-step explanation:
First, divide 100 by 20. You do this because you need something out of 100 to equal a percent. (Example- 50 out of 100 is 50%)
Next you need to take the number you got from dividing (5) and multiply that with 8. This leaves you with 40/100 or 40%.
Hope this helps!
