Since 12 cost $27, you can use compatible numbers to make it ~$28. So, then for 6, it would cost $14 because you just halve everything. Is that what you are getting at?
Answer:
area = 41 units²
Step-by-step explanation:
area = (8 x 4) + (3 x 3) = 41 units²

Answer:
y=4x-3
Step-by-step explanation:
Find the slope for your equation by calculating the change in y over change in x ∆y/∆x or (y2-y1)/(x2-x1)
13-5=8
4-2=2
8/2=4
We now need to use one of these coordinates to finish the equation y=4x+b
5=4(2)+b
5=8+b
b=-3
Now we rewrite our equation in slope int form as y=4x-3
You can check your work by using the other coordinate (4, 13) and see the equation balances.
