Answer:
The manual cost that will take to recreate by the firm is $ 90.51
Step-by-step explanation:
Given:
Number of words the manual contains= 16000
Number of words typed by a clerk in one hour and 20 minutes = 4160
To Find:
The total cost for recreating the manual = ?
Solution:
Step 1: Finding the Number of hours is need to type 4160 words :
= [tex]1\frac{20}{60}[/tex] hours
[tex]\\\\=1\frac{1}{3}[/tex] hours
[tex]\\\\=\frac{4}{3}[/tex] hours
So it takes [tex]\frac{4}{3}[/tex] hours to type 4160 word
Step 2 : Finding the Number of hours is needed to type 1 word
= [tex]\frac{4160}{\frac{4}{3}}[/tex]
=[tex]4160 \times \frac{3}{4}[/tex]
= 3120 words per hour
Step 3 : Finding the Number of hours is needed to type 16000 words
=[tex]\frac{\text{ total number of words}} {\text{ number of words written per hour}}[/tex]
Substituting the values
= [tex]\frac{16000}{3120}[/tex]
= 5.1282 hours
Step 4 : Finding the cost for recreating the manual.
= number of hours x cost per hour
= 5.1282 x $17.65
= 90.51
