Jone has taken a survey of college students and found that 40 out of 42 students studied last weekend. if the college has 8,262 students, what is the best estimate of the number o students who studed last weekend?
A. 8,675
B. 7,869
C. 78,686
D. 43
The ratio of students who studied last weekend to the total number of college students in the survey is 40/42. We can use this ratio to estimate the number of students who studied last weekend out of the total college population.
Let x be the number of students who studied last weekend out of the total college population.
40/42 = x/8262
Cross-multiplying, we get:
42x = 40 * 8262
42x = 330,480
x = 330,480 / 42
x ≈ 7,872
The best estimate of the number of students who studied last weekend is 7,872.
Therefore, the best option is B. 7,869.
