In a store window, there was a box of berries having a total weight of 200 kg.  The berries were 99% water, by weight.  After two days in the sun, the water content of the berries was only 90%, by weight.  What was the total weight of the berries after two days, in kg?

1%200=2            this means that only 2 kg were not water. 

 

let x be the new amount

2=10%x

 

solve for x

2(10)=xx=20

 

20kg is the answer.
