Question 101717: I cant seem to figure out what to do with the data given.
Bob owns a watch repair shop. He is open 5 days per week. Over the years, he has determined that the weekly cost in dollars (in dollars) of operating his shop is given by the cost function: C(x)= 2x^2-57x+26 where x is the number of watches repaired.
What is the daily cost of running the shop if the number of watches repaired is 50?
Thank you for your help

C(x)= 2x^2-57x+26 where x is the number of watches repaired.
What is the daily cost of running the shop if the number of watches repaired is 50?
--------------
The weekly cost is C(50) = 2(50)^2-57(50)+26 = 2176 dollars
---------------
The daily cost depends on how many days he works per week.
If he works 7 days the cost is 2176/7
If he works 5 days the cost is 2176/5
