Question

A store sells pens and note pads in packages. The price of a package of 8 pens and 3 notepads is 4.25. The price of a package of 15 pens and 10 notepads is 11.25.

Answer 1

p = price of pen

n = price of notepad

The price of a package of 8 pens and 3 notepads is 4.25, means:

8 p + 3 n = 4.25

The price of a package of 15 pens and 10 notepads is 11.25, means:

15 p + 10 n = 11.25

Now solve system of tvo equations:

8 p + 3 n = 4.25

15 p + 10 n = 11.25

The solution is:

p = 0.25 , n = 0.75

Price of pen = 0.25

Price of notepad = 0.75
