I think the percent increase is 25% . the original amount they sold was 200 and this season 250. so they sold 50 more peaches. to find percent increase it would be the amount of increase/original amount which would be 50/200 which simplifies to 1/4 which is equal to 25%.
We know that the peaches increase to 50 peaches, so we just need to take 50÷200=25%. As a result, the percent increase is 25%. Okay, let me emphasize this amount of increase means that the amount of increase from 200 peaches to 250 peaches is increasing 50 peaches. And the original price which is 200 peaches, so 25/200=0.25 or 25% as a percent increase. Hope it help!
