If the berries were 99% water, then 1% of the weight was from non-water content.
Let's call the non-water weight "x."
1% of the weight is x:
0.01(weight) = x
Multiply both sides by 100 to solve for weight:
weight = 100x
If the berries originally weighed 200 kg, then the weight of non-water content was:
weight = 100x = 200 kg
x = 2 kg
So the original 200 kg was made up of 2 kg of non-water content and 198 kg of water.
After two days in the sun, the water content decreased to 90%. Now, 10% of the weight is from non-water content.
Let's call the new weight "w."
10% of the weight is x:
0.1(w) = x
We know that the non-water content stays the same, so:
2 kg = x
Substitute this value of x into the equation for weight:
w = 100x/0.1 = 100(2)/0.1 = 2000 kg
Therefore, the total weight of the berries after two days in the sun was 2000 kg.
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?
