Question 1170977: Cadbury 9 chocolate bar costs 12.00 per piece. However, if you buy more than 20 pieces, they will be marked down to a price of 10.00 per piece. Use a piecewise function to represent the cost in terms of number of chocolate bars bought.

You can put this solution on YOUR website! .
As the problem is worded, printed, posted and presented, it is UNCLEAR,
if the discounted price of $10.00 per piece is applied to the entire purchase
or to its part, which is over of 20 pieces, ONLY.
Please clarify.
It is a typical and standard mistake of unprofessional writers/(problem composers).
