 We have boxes colored either red or blue. In each blue box, there is a fixed number of blueberries. In each red box, there is a fixed number of strawberries. If we dispose of one blue box for one additional red box, the total number of berries would change by a certain amount, and the difference between the total number of strawberries and the total number of blueberries would increase by 100. Each blue box contains 35 blueberries. What is the change in the total number of berries? Show your work in <think> </think> tags. And return the final answer in <answer> </answer> tags.<|im_end|>
