Question

A manufacturing plant is looking at units shipped for a 3-year period. In 2005, the plant shipped 12,500 units. In 2008, the

plant shipped 16,000 units. Find the rate of change of units shipped over the 3-year period.
A. 3,500/
2,008
B. 3,500/
2,005
C. 3,500/3
D. 9,500

Answer 1

Option C - 3500/3

Explanation:

Step 1 :

Number of units shipped in the year 2005 = 12,500 units

Number of units shipped in the year 2008 = 16,000 units

Time period = 3 years

We have to determine the rate of change of units over the 3 year period. This is obtained by dividing the difference in units by the time period.

Step 2:

The difference in units over the 3 year period = 16000 - 12,500 = 3500 units.

Hence the required change rate over the 3 year period = 3500/3

Option C is the answer.
