Answer:
0.41 × 570 = 5.7+228 = 234.
Step-by-step explanation:
If the 100 students are an accurate sample
(not a random sample, but chosen by first asking all 570 students the question and choosing 100 to reflect the proportion, and assuming they didn't change their answers and didn't lie)
then 41% of students have multiple pets so 0.41×570=234 have multiple pets.
