The answer is to call me quick
Let the total cost of the item be represented by C and the price be represented by P, then given that t<span>he total cost of an item including sales tax is directly proportional to its price, thus</span>

where k is a constant.
Given that <span>the total cost of a $32 item is $33.60, thus

Therefore, the total cost on a $55 item is given by

</span>
first you need to find the slope (m) using y2-y1/x2-x1.
-4-2/4-1= -6/3=-2
m=-2
then plug into the intercept form formula: y-y1=m(x-x1)
y-2=-2(x-1)
I think that person above me should be your answer
