obviously A. the only difference is paying for the first pound of the second package. if it's included with the first one, its price is Y, if mailed separately X. Then the difference is X-Y.

agree with A. I just did the math on paper.

separately, you have one pkg costing X+2Y, and the other costs X+4Y. Together, thats 2X+6Y.

Together, the cost is X+7Y. The difference btwn the two options ix X-Y.

Another way of solving this problem is using numbers in place of x and y
choose x = 3 and y = 2 as x>y

Shipping separately :
3 lb Package: 3 + 2 *2 = 7
5 lb package: 3 + 4*2 = 11
Total cost: 18 lbs

Shipping combined:
Cost = 3 + 7 * 2 = 17 lbs

So shipping combined is cheaper it is cheaper by 1cent(i.e 3-2 or x-y)

Looking at the answer choices - A

(A) Combined, with a savings of x - y cents
(B) Combined, with a savings of y - x cents
(C) Combined, with a savings of x cents
(D) Separately, with a savings of x - y cents
(E) Separately, with a savings of y cents


Shipping separately costs 1x+2y for the 3 pounds package (x cents for the first pound and y cents for the additional 2 pounds) plus 1x+4y for the 5 pounds package (x cents for the first pound and y cents for the additional 4 pounds), so total cost of shipping separately is (x+2y)+(x+4y)=2x+6y;

Shipping together in one 8-pound package costs 1x+7y (x cents for the first pound and y cents for the additional 7 pounds);

Difference: Separately-Together=(2x+6y)-(x+7y)=x-y --> as given that x>y then this difference is positive, which makes shipping together cheaper by x-y cents.

Answer: A.
