Question

A car wash services 200 customers an hour on a lovely Saturday afternoon. The car wash employs 5 washers at $6 per hour and uses $50 of water and $5 of electricity per hour. They charge $10 per car for their standard wash job. What is the new productivity if they decrease wages by 1%?

Answer 1

Answer: $69.19

Step-by-step explanation:

Wage = $6 per hour.

Employees = 5

Electricity = $5

Water usage = $50

Charges per car = $10

Customers serviced per hour = $200

Decrease in wages by 1%

= )wage / 100.

= $6 / 100

= 0.06

= 6-0.06 = $ 5.94

Productivity = output/ input

= 200 x $10+ $50+ $5 / 5 x $5.94

= $2055 / $29.7

= $69.19
