Work the following pricing problems for services rendered. (round to tenths.)

labor rate = $8.00 per hour
labor time = 6 hours
retail price of parts = $0
total job cost = $86.00
overhead rate?

Overhead rate = $6.3

Step-by-step explanation:

Given : Labor rate = $8.00 per hour

Labor time = 6 hours

Retail price of parts = $0

Total job cost = $86.00

To find : Overhead rate

Solution:

Overhead cost =  Total Cost - The cost of all inputs

The Overhead Rate is this number divided by total labor hours.

Total job cost = $86.00

Labor Cost = labor rate × labor time = 8 × 6 = $48

Retail price of parts:$0

Overhead Costs = total cost - labor cost= $86 - $48 = $38

Now, we divided overhead cost by labor hours to get overhead rate,

Overhead Rate 

Therefore, Overhead rate is $6.3

x = ±sqrt(10)

step-by-step explanation:

5 - 2x² = -15

subtract 5 from each side

5-5 - 2x² = -15-5

-2x^2   = -20

divide by -2 on each side

-2x^2   /-2= -20/-2

x^2 =10

take the square root on each side

sqrt(x^2 )=±sqrt(10)

x = ±sqrt(10)

check:

5 - 2x² = -15

+sqrt(10)

5 - 2(sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15

-sqrt(10)

5 - 2(-sqrt(10))² = -15

5 -2(10) = -15

5 -20 = -15

-15 = -15
