The correct numbers are 55 and 47, because they have a difference of 8 and a sum of 102.
To formulate the equation that shows the cost of 10 pounds of potatoes is 8 dollars we proceed as follows;
suppose the cost 1 pound is x;
thus,
total cost=(amount in pounds)*(price of one pound)
total cost=$8
amount=10 pounds
cost of one pound=x
thus the equation is;
8=10x
7x20 = 140 making that the total amount of decrease per week. Hope this helps!
