To estimate how many middle school students will select french fries as their favorite fast food, we can use a proportion.
First, we can set up the proportion:
21/50 = x/350
where x represents the number of middle school students who will select french fries as their favorite fast food.
To solve for x, we can cross-multiply and simplify:
21 * 350 = 50 * x
7,350 = 50x
x = 147
Therefore, we can estimate that approximately 147 middle school students at King's High School will select french fries as their favorite fast food.
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.
