The salary and benefits for the clerk cost the firm approximately $17.65/hour. How much will recreating the manual cost the firm?

Answer 1

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 :

=
`1(20)/(60)` hours

`\\\\=1(1)/(3)` hours

`\\\\=(4)/(3)` hours

So it takes
`(4)/(3)` hours to type 4160 word

Step 2 : Finding the Number of hours is needed to type 1 word

=
`(4160)/((4)/(3))`

=
`4160 * (3)/(4)`

= 3120 words per hour

Step 3 : Finding the Number of hours is needed to type 16000 words

=
`\frac{\text{ total number of words}} {\text{ number of words written per hour}}`

Substituting the values

=
`(16000)/(3120)`

= 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
