First, let's calculate Mark's current weekly operating expenses:
Current rate: $68.75/hr
Number of hours rented per week: 18.5
Weekly operating expenses = 18.5 hrs/week * $68.75/hr
Weekly operating expenses = $1,271.88/week
Next, let's calculate the new hourly rate after the increase:
New hourly rate = $68.75/hr + ($68.75/hr * 2.25%)
New hourly rate = $68.75/hr + $1.546875/hr
New hourly rate = $70.296875/hr
Now, let's calculate Mark's new weekly operating expenses:
New weekly operating expenses = 18.5 hrs/week * $70.296875/hr
New weekly operating expenses = $1,301.17/week
Finally, let's find the increase in his weekly operating expenses:
Increase in weekly operating expenses = New weekly operating expenses - Current weekly operating expenses
Increase in weekly operating expenses = $1,301.17/week - $1,271.88/week
Increase in weekly operating expenses = $29.29/week
Therefore, the increase in his weekly operating expenses will be $29.29.
