Answer 1

15

Explanation:

Answer 2

Percentage loss in weight is 14.5833 %

Solution:

Given that Labrador retriever weighs 48 kg

After a diet and exercise program the dog weighs 41 kg

To find: percentage loss in weight

Steps to follow:

First: work out the difference (decrease) between the two numbers you are comparing. Then: divide the decrease by the original number and multiply the answer by 100

`\text {percentage loss }=\frac{\text {final value - starting value}}{\text {starting value}} * 100`

Here starting value = 48 kg and final value = 41 kg

`\begin{array}{l}{\text { percentage loss }=(41-48)/(48) * 100} \\\\ {\text { percentage loss }=(-7)/(48) * 100=-14.5833 \%}\end{array}`

Negative sign indicates percentage loss(decrease in weight)

Thus percentage loss in weight is 14.5833 %
