Step-by-step explanation:
The average rate of change is
f(x2) - f(x1)
-----------------
x2-x1
We want to find the change from 1 to 3
f(3) = 8
f(1) = 2
f(3) - f(1) 8-2 6
----------------- = ------------ = ---- = 3
3-1 2 2
Only the first one is a function
functions can’t have more than one of the same x value
An equation that can be used is 3T + 18B = 450. Since they know they need 30 towels, substitute 30 for T. The equation becomes 3(30) + 18B = 450. Simplifying, 90 + 18B = 450. Subtract 90 from each side, 18B = 360. Finally, divide each side by 18, B = 20. The maximum number of basketballs that may be purchased is 20.
