A fruit company delivers its fruit in two types of boxes. large and small. A delivery of 3 large boxes and 5 small boxes has a total weight of 75 kilograms. A delivery of 9 large boxes and 7 small boxes has a total weight of 171 kilograms. How much does each type of box weight?

15.5 kg

Step-by-step explanation: x=wt of small box     y = large box wt

First delivery

   5x  + 2y = 96      solve for y = (96-5x)/2

Second Delivery

  8y + 3x = 163       Substitute for y

  8 ( ( 96-5x)/2 ) + 3x = 163       and solve for x

   384 - 20x +3x = 163

17x=221

x=13   =   small box wt   kg               y= (96-5x)/2 = large box wt = 15.5 kg
