Answer:
x≥ 19
Explanation:
Let the price of an amusement park ticket is x
If the price of an amusement park ticket is no less than x, therefore, it has to be x or greater than x;
The inequality sign to be used will be the greater than or equal to sign (≥). Hence the required inequality is x≥ 19 where x is the price of an amusement park ticket.
