Nathan is going to a water park today. He knows that the cost of admission is at least $12 per person. If c stands for the cost of admission, which of the following inequalities represents the cost of admission for the water park?
If the cost c is at least $12 then it could be equal to 12, or could also be a cost greater than $12. So, c is greater than or equal to 12, expressed as c $12
