The spoilage rate on a shipment of wheat is expected to be 20%. it was purchased at a cost of $5.35 per bushel. what should the selling price per bushel be to achieve a markup of 6% based on selling price? (round your answer to the nearest cent)

$7.09

Step-by-step explanation:

Let wheat shipment be x bushels

Per bushel cost = 5.35

So x bushels cost = 5.35x

Achieving markup of 6% means 1.06 * 5.35x =5.671x

20% spoiled means 80% of x stays, so 0.8x will need to be sold at 5.671x

Selling price should be 5.671x/0.8x = $7.09

So that's 7 dollars and 9 cents

  (1)  -5 and -3

Step-by-step explanation:

Descarte's rule of signs tells you the lack of sign changes among the coefficients means there are no positive real roots. That eliminates all answer choices except the first one.

If you want to go to the trouble, you can factor the equation:

  y = (x +3)(x +5)

These factors are zero when x = -5 and x = -3.
