Answer:
The relation has an undefined slope if the graph line is just vertical.
If each there are 40 pencils, then divide to find how much each pencil is.
37.20 / 40 = $0.93
Correct answer is D.
After solving, we see that buying the case of 40 pencils is cheaper than buying 40 individual pencils.
Hope This Helped! Good Luck!
I dont know if this will help you, but a 15th (.15) of an hour is 9 minutes!
So it'd be
.15=9 minutes
.30=18 minutes
.45=27
.60=36
.75=45
.90=54
and obviously
1.0 is 60 minutes
(((EVERY .05 IS THREE MINUTES))))
The answer is 4
3 times 4 equals 12
A way to get the answer is by dividing 12 by 3 and you get 4 as well
