Answer:
8
Step-by-step explanation:
c^2 is 9, 2d is 4
9-4+3=8
It is 63 students, because 84 divided by 2 is 42 then half of 42 is 21 so 21 is 25% so then you do 21 x 3 = 63
The next 18 days because your trying to see how many days it is until he does BOTH
28 divided by 4 = 7
so do 7 * 5 which is 35 so they make 35 cookies in 5 seconds
