Answer:
To find out how long it will take Oscar to clean 75 transparencies at a rate of 17 transparencies in 10 minutes, you can set up a proportion:
(17 transparencies / 10 minutes) = (75 transparencies / x minutes)
Now, solve for x:
x = (10 minutes * 75 transparencies) / 17 transparencies
x = (750 minutes) / 17 transparencies
x ≈ 44.12 minutes
So, it will take Oscar approximately 44.12 minutes to clean 75 transparencies. Therefore, option (a) is the correct answer.
