What expression can be used to calculate the rate per minute at which the air freshener dispenses sprays?

okay so lets say that it sprays every 12 seconds so what you need to do is divide 12 with 60 so  60÷12=5 so it sprays 5 times per minute 

You didn't give any answers, but, I hope this will help you out a bit:


for example, if the air freshener sprays 3 times every 20 minutes,

here are our points:

(20,3), (40,6), (60,9), (80,12)

lets take the second and third point to find the slope.

[tex]\frac{9-6}{60-20} = \frac{3}{40}[/tex]

3/40 would be the slope.
