Answer:
40 students
Step-by-step explanation:
We need a system of equations to find x or the students in advance:
2x + 4y = 800
x + y = 220
We can use substitution and isolate y in the second equation, which gives us y = 220 - x.
When we plug this into the first equation, we get 2x + 4(220 - x) = 800 and solving for x gives us x = 40.
I believe the answer is 40%
Not entirely sure, hope I helped though!

Step-by-step explanation: #1 is 5 because 5/1 is in the m slot and #2 is 2
Dividing the number of balloon animal per the time he takes to make them you get an average of how many animals per minute Fred the clown can make.
20/15=1,3 animals per minute
Since 0,3 is not a complete animal, the correct answer would be "Fred the clown can make 1 animal in 1 minute"
