B. is the right option... hope it helps

The constant rate of change is $1.75 :)
This is because when the x value equals 1 the y value equals 4.75. And when the x value equals 2 the y value equals 6.50, so the rate of change is between the 2 y values which is linear so it has a constant rate of change of $1.75.
40/100 = 22/x
40x = 2200
x = 55
There are 55 students in this class.
Answer:
Step-by-step explanation:
The exponential growth equation that represents the rabbit population y) after x years is y = 500(1.25)ˣ
Exponential growth is given by:
y = abˣ
where a is the initial value of y, b is the multiplier and b>1, y, x are variables.
Let y represent the total rabbit population after x years.
Since there were 500, introduced hence a = 500. Also the population increases 25% each year, hence:
b = 100% + 25% = 1 + 0.25 = 1.25
y = 500(1.25)ˣ
The exponential growth equation becomes y = 500(1.25)ˣ
