Leblanc company had the following department data: physical unitswork in process, july 1 18,000completed and transferred out 81,000work in process, july 31 27,000materials are added at the beginning of the process. what is the total number ofequivalent units for materials in july?

FIFO  90,000

W/A  108,000

Explanation:

There are two method for process costying FIFO and Weighted Average (WA)  as there is no indication we will do both:

The difference is that FIFO discriminate bwetween started and completed units and completed units. therefore, the complete beginning inventory is subtracted.

As the materials are added at the beginning of the period then both, beginning and ending are at 100%

completed units             81,000

ending WIP                    27,000

beginning WIP             (18,000)  

equivalent units FIFO   90,000

complete units                                      81,000

ending WIP                                           27,000  

equivalent untis Weighted average  108,000

When the ball hit the ground, the height of the ball will be zero. So using the value of h(x) as zero in the given equation, we can find the time in which the ball will hit the ground.

0 = -(x-2)^2 + 16

(x-2)^2 = 16

x-2 = 16

x-2 = 4

x = 6

This means the ball will hit the ground 6 seconds after Amir threw it.
