Carrie asked 50 randomly selected middle school students at King’s High School about their favorite fast food item. Twenty-one selected french fries. If there are 350 middle school students at King’s High School, estimate how many will select french fries as their favorite fast food.

Question

A. 141
B. 147
C. 153
D. 159

Answer 1

We can set up a proportion to solve for the estimated number of students who will select french fries:

21/50 = x/350

Cross-multiplying, we get:

50x = 21 * 350

Simplifying, we get:

50x = 7350

Dividing both sides by 50, we get:

x = 147

Therefore, the estimated number of middle school students at King's High School who will select french fries as their favorite fast food is 147.

The answer is B. 147.
