Total number of doughnuts sold and given away per week = k
Total number of doughnuts sold and given away in 8 weeks = 8k
Number of doughnuts given away in 8 weeks = 8k/2 = 4k
Selling price of a doughnut = .25 $
Dollar worth of doughnuts given away = 4k*.25 = k

1 week = k doughnuts sold.
Actual number of doughnuts for which the price is charged = k/2
Number of weeks = 8
Number of doughnuts sold in 8 weeks for which the price is charged = 8*(k/2) = 4k
Price of each doughnut sold = 0.25
Price of 4k doughnuts = 0.25*4k = K

Total number of donuts sold and given away in a week =K =(K/2 + K/2)=(sold + free)
cost of each donut =$0.25
no of free donuts in a week= 0.25*K/2=K/8
in 8 weeks time 8*K/8 =K

in one week \(\frac{k}{2}\) doughnuts are given away because the question prompt says that the promotion gives away one doughnut for every doughnut purchased so if \(K\) doughnuts per week is inclusive of the number of given away and sold then \(\frac{k}{2}\) doughnuts were given away in a week and \(\frac{k}{2}\) doughnuts were sold in a week.

in one week
\(0.25*\frac{k}{2}\) dollars worth of doughnuts were given away
\(= \frac{k}{8}\) dollars worth of doughnuts given away in one week

the question mentions an 8 week period so
\(8*\frac{k}{8}\)
\(= k\) dollars worth of doughnuts were given away during the period

thus answer is C
