There are 20 children at a library. Six of the children have an average age of 5 years. The remaining children have an average a
Allushta [10]
Answer: The average age is 7.1 years.

This problem is an example of when we need to take a weighted average. We simply can't just find the average of 5 and 8, because there are different children of each each.

To start, lets multiply the total number of children by their individual ages.

6 x 5 = 30 years
14 x 8 = 112 years

There are 142 years among the 20 years, so divide 142 by 20. This gives us an average age of 7.1 years.

A markup of 33% based on cost is desired for a load of 800 bushels of peanuts. They were purchased at $5.85 per bushel. What sho
Alenkasestr [34]

Answer: Option 'c' is correct.

Step-by-step explanation:

Since we have given that

Number of bushels of peanuts = 800

Price of each bushels of peanuts = $5.85

And there is mark up rate = 33%

So, Total price would be

1.33\times 800\times 5.85\\\\=\$6224.4

If there is spoilage rate = 21%

So, the remaining rate would be 1-0.21=0.79

so, Number of remaining bushels of peanuts would be

0.79\times 800\\\\=632

So, Selling price per bushel would be

\dfrac{622.4}{632}\\\\=\$9.85

Hence, Option 'c' is correct.
