Question
Write an inequality to represent the following:
The ticket to the movie costs $10. How much money should Kristin take with her?
Let x represent the amount of money Kristin takes with her.
- x > 10
- x ≥ 10
- x < 10
- x ≤ 10
Hint:
We are given a statement. We have to write the expression of inequality for the given statement. We have to see the limits given for the required value.
The correct answer is: x ≥ 10
The given statement is as follows:
Ticket to the movie costs $10.
We are asked how much money Kristen needs to take with her.
The variable x represents the amount of money.
The cost of the ticket is $10. So, Kristen will need at least this much amount. She cannot take less than this. But, she can take money greater than this amount.
So, the variable x can be greater than or equal to 10.
The sign for greater than or equal to is “≥10”
The mathematical representation of the inequality is as follows:
x ≥ 10
This is the given inequality.
For such questions, we have to be careful about the limits.
