Answer:
22 hens and 78 sheep
Step-by-step explanation:
Let the number of hens = x
Number of sheep = y
Total heads = 100
x + y = 100 --------------------(I)
x = 100 - y
Number of legs of 'x' hen = 2*x = 2x
Number of legs of 'y' sheep = 4*y = 4y
total legs = 356
2x + 4y = 356 -----------------------(II)
Substitute x = 100 -y in equation (II)
2(100 - y) + 4y = 356
2*100 - 2*y + 4y = 356
200 <u>- 2y + 4y</u> = 356 {Combine like terms}
200 + 2y = 356 {Subtract 200 from both sides}
2y = 356 - 200
2y = 156 {Divide both sides by 2}
y = 156/2
y = 78
Plugin y = 78 in equation (I)
x + 78 = 100
x = 100 - 78
x = 22
22 hens and 78 sheep

We compute the productivity percentage change of each category using the formula:
Productivity percentage change for each category
1) Units produced:
2) Last (hours)
3) Resin (pounded)
4) Capital invested ($)
5) Energy (BTU)
2) Improvement for labour hours
From the previous computations, we see that the percentage change of the category "Last (hours)" has a negative value of -8.33%, which means that this value decreased by 8.33% with respect to the last year.
Answer
1) Productivity percentage change for each category
0. Units produced: ,0%
,
1. Last (hours): , -8.33%
,
2. Resin (pounded):, -10%
,
3. Capital invested ($): ,10%
,
4. Energy (BTU): ,-5%
2) Improvement for labour hours
The percentage change of the category "Last (hours)" has a negative value of -8.33%, which means that this value decreased by 8.33% with respect to the last year.
