Final answer:
Jack has 33 airplanes now.
Step-by-step explanation:
To find out how many airplanes Jack has now, we need to calculate 32% of his original collection and add it to the original number. First, calculate 32% of 25 by dividing 32 by 100 and then multiplying the result by 25. This gives us 8. Then, add 8 to 25 to find the total number of airplanes Jack has now. Therefore, Jack has 33 airplanes now.
