We can assume 100 tons of soybeans were produced in year X, and the selling price of soybeans is $100 per ton. So in year Y, the soybean production was 125 tons but the selling price was $75 per ton.
We can see that in year X, the revenue was 100 x 100 = $10,000 and in year Y, the revenue was 125 x 75 = $9,375. We see that this is approximately a 6% decrease (if it were exactly a 6% decrease, the revenue in year Y would be $9,400).
