A shop produces sarongs. The daily average production is given by 5n + 20, where n is the number of workers aside from the owner. In the first k days, 500 units are produced, and then 5 workers are added to the team. After another k days, the cumulative total is 1100. How many workers were part of the latter production run?	Choose the correct choice from the following choices:
A) 26  B) B)10  C) C)11  D) D)15  E) E)23.5
The daily average production is given by 5n + 20- given   In the first k days, 500 units are produced   = (5n+20)K =500   k = 500/5n+20...................................1   5 workers were added = 5(n+5)+20 = 5n +45   cumulative is 1100 .. thus for the current period = 1100 -500= 
<gadget id="calculator">1100 -500</gadget>
<output>600</output>
600   (5n+45)K= 600   k = 600/5n+45........................................2   equate 1 and 2   500/5n+20 = 600 /5n+45   500(5n+45) = 600(5n+20)   2500n + 22500 = 3000n + 12000   -500n = -10500   n = 21   thus n+5 = 26   hence 26
