Answer:
The net profit rate on the book is 5.41
Step-by-step explanation:
Given as :
The marks up percentage of book = m = 40%
The overhead rate is 16% of selling price
The cost price of book = c.p = $18.10
Let The profit = $p
Let The selling price = s.p
<u>Now, According to question</u>
mark up percentage =
I.e 40% =
Or, + 1 =
Or, =
Or, s. p =
∴ s.p = $25.34
So, selling price of book = s.p = $25.34
Now, The overhead percentage = 16%
i.e overhead rate =
Or, estimated cost = 16% × 25.34
I,e estimated cost = 0.16 × 25.34
∴ estimated cost = $4.05
Now,
Profit = selling price of book - estimated book cost
I.e p = $25.34 - $4.05
∴ p = $21.29
So, The profit rate% =
I.e The profit rate% =
∴ profit rate %= 5.41
So, The profit rate = p = 5.41
Hence, The net profit rate on the book is 5.41 Answer

Answer:
The answer would be 3.606, but rounded is 3.61, or 3.6
Step-by-step explanation: A^2+B^2 = c^2, so 3x3=9
2x2=4,
9+4=13
Then square 13, which would give you 3.606
