Total Cost?
Quantity of Good Potatos?

125%2Akg%2A125%2A%28dollars%2Fkg%29=15625%2Adollars

125-5=120%2Akg, of good potatos

The cost plus 20% of this cost, 15625%2B%281%2F5%2915625=%281%261%2F5%29%2A15625=18750%2Adollars, the revenue needed for the profit.

The unit PRICE is %2818750%2F120%29%28dollars%2Fkilogram%29=highlight%28156.25%28dollars%2Fkilogram%29%29.
