Answer 1

Answer:

Each pencil = 4 ,

Each pen = 8.

Step-by-step explanation:

The cost of 6 pens and 3 pencil is 60, while 5 pens and two pencil is 48. What is the cost of each pen and pencil?

Let a pen cost S and a pencil L.

6S + 3L = 60, or

2S + L = 20 …(1)

5S + 2L = 48 …(2)

Multiply (1) by 2 to get

4S + 2L = 40 …(3)

Subtract (3) from (2)

S = 8. So each pen is 8.

From (1), L = 20 - 2S = 20–16 = 4.

Each pencil is 4 and each pen is 8.
