Posted this one a few days ago, here goes again...
Let us call the cost function
c(w) = .07w + 13.3
Now if the number of wing nuts, w, is 375, we substitute that in for w and get
c(375) = .07(375) + 13.3
c(375) = 26.25 + 13.3
c(375) = $39.55
To find the average cost, we divide that total cost by 375 wing nuts and get
$39.55 / 375 = $.1055 or 10.55 cents each
