At a charity event, attendees can donate in different increments to support the cause. The minimum donation amount is $25, and each subsequent amount can be either $50 or $75. Last year, the charity raised a total of $2,500 from these donations. If the number of $25 donations was twice the number of $50 donations and the number of $75 donations was 10 less than the number of $50 donations, how many donations of each type were made?
