------------------------------------------------
~Turn into decimal
40% = 0.4
~Multiply
200 * 0.4 = 80 (7th graders in the band)
Now, we can write this as 80 is 20% of what number.
~Turn into decimal
20% = 0.2
~Divide
80 / 0.2 = 400
------------------------------------------------
Hence, there are students in band!

A bicyclist travels at a constant speed of 12 miles per hour for a total of 45 minutes.
We know the formula , Distance = speed * time
Speed is constant and it is 12. So it is linear
The function becomes d = 12t, x is the t is the time and d is the distance
At the starting point, t=0 and distance d=0
End point , t=45 min = 0.75 hours and distance = 12 * 0.75 = 9
So domain (t) is {}
Range (d) is {}
