To mail a package, the rate is x cents for the first pound and y cents for each additional pound, where x>y. Two packages weighing 3 pounds and 5 pounds, respectively can be mailed seperately or combined as one package. Which method is cheaper and how much money is saved?A. Combined, with a saving of x-y centsB. Combined, with a saving of y-x centsC. Combined, with a saving of x centsD. Separately, with a saving of x-y centsE. Separately, with a saving of y cents

Option A) Combined, with a saving of x-y cents      

Step-by-step explanation:

We are given the following in the question:

The rate to mail a package is x cents for first pound and y cents for each additional pound.

Weights of packages =

3 pounds and 5 pounds

Cost of combined package:

Total weight = 8 pounds

Cost of sending separately:

Difference between cost of sending the packages separately and combined

Thus, sending the packages combined is a cheaper method with a saving of (x-y) cents

Thus, the correct answer is:

Option A) Combined, with a saving of (x-y) cents

bull

step-by-step explanation:

look at the picture.

y-intercept for the function on a picture is 4 → point (0, 4).

y-intercept for the function

is for x = 0. substitute:

y-intercept is 8 → point (0, 8).
