The weighted average unit cost after the October 22 purchase is $13.70.
<h3>What is the weighted average unit cost?
</h3>
The weighted average unit cost determines the weighted average cost of all the purchased inventory.
[(300 x 12) + (390 x 15) ] / (300 + 390)
(3600 + 5850) / 690 = $13.70

The number 3 will appear in the numbers 3, 13, 23, 30, 31, 32, 33, 34, 35, 36, 37, 38, 39, 43, 53, 63, 73, 83, 93. In these numbers it appears 20 times.
Answer: Option a.
Step-by-step explanation:
The equation of the line in Slope-Intercept form is:
Where "m" is the slope and "b" is the y-intercept.
Find the slope of the line with this formula:
Choose two points from the table and substitute the coordinates into the formula. Then, the slope is:
By definition, the line intersects the y-axis when the value of "x" is zero. So, based on the table, the y-intercept is:
Then the equation of the line is:
The line intersects the x-axis when the value of "y" is zero, then substituting y=0 into the equation of this line, and solving for "x", you get:
So, the point of intersection with the x-axis is:
Since the table shows the amount of air leaking from an inflatable as a function of time, you can conclude that meaning of the x-intercept in this scenario is: "The time it takes all the air to leave the inflatable".
