Answer:
$7.09
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
