Y = -2.8x +69.4
Let y represent units of inventory, and x represent days since the last replenishment. We are given points (x, y) = (3, 61) and (13, 33). The line through these points can be described using the 2-point form of the equation of a line:
... y -y1 = (y2-y1)/(x2 -x1)(x -x1)
Filling in the given point values, we have ...
... y -61 = (33 -61)/(13 -3)(x -3)
Simplifying and adding 61, we get ...
... y = -2.8x +69.4

Answer:
$43.20
Step-by-step explanation:
A swimsuit that originally cost $90 before any discount is on sale for 20% off.
X = price of swimsuit
X = 90
20% off = 90 * 0.8 = 72
The swimsuit is then put on clearance for an additional 40 % off the sale price.
72 * 0.6 = 43.2
what is the final price?
$43.20
