Question

Each day at lunchtime, at least 53 people buy food from a food truck.

Using the variable p, an inequality that represents that situation is...

Answer 1

p ≥ 53.
p (the number of people) is at least (so, greater than or equal to) 53

Answer 2

p≥ 53

Explanation:

Given that, at least 53 people buy food from the food truck. It means minimum 53 people buy the food, and number greater than 53 is quite possible; however, the possibility of people buying food less than 53 is not possible.

Since the number of people is alway 53 or greater than 53 therefore we may represent this condition using the greater and equal sign.

Lets use the variable p for people who buy the food.

Now the inequality can be written as

p≥ 53

So our desired inequality is p≥ 53 .
