6. A trader sold 100 boxes of fruit at
Maurinko [17]

Answer:

GH¢ 5.80 per box (average)

Step-by-step explanation:

In order to find the average selling price per box we first need to sum up all of the boxes to get the total number of boxes. Then we need to sum up the amount of money that he made by multiplying the cost per box by the amount sold at each price and adding those values together. Finally, we need to divide the total money made by the total number of boxes sold to get the average selling price per box.

100 boxes + 800 boxes + 600 boxes = 1,500 total boxes

(100 * 8) + (800 * 6) + (600 * 4) = total money made

800 + 4800 + 2400 = GH¢ 8,700 total money made

GH¢ 8,700 / 1,500 = GH¢ 5.80 per box (average)
