Answer:
D. The unit rate is 10 minutes per day.
Step-by-step explanation:
Lets define our terms:
X = Number of days
Y = Total practice time
Remember that ordered pairs look like this (x,y) so in this case it would be this:
(number of days, total practice time)
We are given point (2,20). It can be reworded like this:
(2 days, 20 minutes of practice time)
But, we can simplify this down to this:
(1 day, 10 minutes of practice time)
Therefore, the only answer that makes sense is the unit rate is 10 minutes per day.
I hope this helps!!
