-BARSIC- [3]

Answer:

The weight of large and small box are 18.25 kg and 13.25 kg respectively.

Step-by-step explanation:

Let the weight of large and small box are x and y respectively.

It is given that a delivery of 5 large boxes and 3 small boxes has a total weight of 131 kilograms.

$5x+3y=131$ .... (1)

A delivery of 2 large boxes and 6 small boxes has a total weight of 116 kilograms.

$2x+6y=116$ .... (2)

On solving (1) and (2) using graphing calculator, we get

$x=18.25$

$y=13.25$

Therefore the weight of large and small box are 18.25 kg and 13.25 kg respectively.
