Here, we want to get the image of the point (-5,-6) after the reflection

Mathematically if we reflected a point with the pre-image coordinates (x,y) over the line y = -x; its image becomes (-y, -x)

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
kompoz [17]

Answer:

$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
