Choice B and Choice C
====================================================
Reasoning:
c = cost of one crate (some unknown amount in dollars)
c+20 = cost of a crate and a leash
5(c+20) = cost of five sets of items mentioned
5(c+20) = 475 is one equation we can form
5c+100 = 475 is another equation we can form
I used the distributive rule to go from 5(c+20) to 5c+100.
The 100 indicates that the five leashes combine to $100, since 5*20 = 100.
The 5c represents the cost of all five crates combined.
So 5c+100 is another way to express the total cost of all five crates and all five leashes.
---------------
Side note: Solving either equation leads to c = 75, meaning that each crate costs $75.
p(not A)=0.18
p(A&B)= 0.44
A= 0.44- 0.18
= 0.26
P(B given A)= 0.26+0.18+0.44
=0.7
So the rise/run is -4/1 (since the line goes down 4 units when it hits a line directly, and wherever the line hits (in this case unit 1 on the x-axis)). This will be your m. Slope intercept form is y=mx+b, therefore your equation will be y==4/1x+b. to find b, you need to look at where the line hits the y-axis. It hits it at point 4. therefore your final answer will be y=-4/1x+4
