Which inequality could be used to represent the situation: you must donate at least $5 to get free popcorn

x ≥ 5

Step-by-step explanation:

If we represent the donated amount by x, according to the problem x must have a value of at least $5 (because of the expression "you must donate at least $5").

This can be represented by the following inequality:

x ≥ 5

Where the symbol  ≥ means "greater than or equal" which is the requirement in this case. So when reading the inequality x ≥ 5 we are saying that you must donate an amount equal to or greater than $ 5
