20 edges
F=12, V=10
V -E+F=2
10-E+12=2
-E+22=2
-E=-20
E=20
You'd divide $19.32 by $.69, that is 28 donuts then you'd subtract 24 from 28 to find out how any MORE donuts she bought than two dozen so the answer is 4 donuts.
Answer: 
Step-by-step explanation:
We write a function f(x) which gives the values of the function that are dependent on the independent variable "x".
Given: The number of miles on the odometer can be represented by the equation y = x + 40, 000, where y is the number of miles on the odometer, and x is the number of miles you have driven it.
Here y is dependent on x, so we replace y by f(x), then we get
which is the required answer.
We can’t draw it on paper LOL
