Answer: The answer will be 24 as an whole number. But as an percent it will be 2400%.
Step-by-step explanation: I know this because, 25 + 35 will equal to 60. So, 17 + 19 will equal to 36. therefore, you will have to subtract 36 from 60 and you will get 24. You also asked for the percentage, which is 2400%.
