Answer:
Bill has $25,000 at-risk and he can also deduct $25,000 from his income due to the losses associated with his rental activity.
Explanation:
At risk amounts are the money that investors can lose due to a bad business decision or performance. The maximum amount that an investor can deduct is equal to the at-risk amount that he/she has invested.
Bill's at-risk $25,000 are equal to the money he spent on house repairs.
