+866 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?
+208 1% x 200 = 2
so 2kg of berries did not change.
198kg were water.
10% of the water were gone.
10% x 200 = 20
That means now 178kg were now water
So 178+2 = 180
