In a store window, there was a box of berries having a total weight of 200 kg. The berries were 98% water, by weight. After two days in the sun, the water content of the berries was only 95%, by weight. What was the total weight of the berries after two days, in kg?

First off, if the 98% of the berries were water, that means that only 2% of the berries weren't water.

We have \(2/100 \cdot 200 = 4\), so 4 kg weren't water.

Now, since a lot of it evaportated, that means there is less water.

HOWEVER, the weight of the non-waters stays the same.

That means that 4kg is 5% of the total weight.

We have \(4*20 = 80\), so 80 kg is our answer.

80 is our final answer!

Thanks! :)
