use inequslity notation to describe the set of any numbers. Define any variables you use.
No item at Sarah's Variety Store cost more than $2.00.
The price of a gallon of gasoline varies from $1.099 to $1.399.
Need help please
To describe the set of any numbers using inequality notation, we can use a variable to represent the numbers and an inequality symbol to indicate the range of values. Let's define some variables and use them to describe the given scenarios.
1. No item at Sarah's Variety Store cost more than $2.00:
Let's define the variable "x" to represent the price of an item. Since no item costs more than $2.00, we can write the inequality as:
x ≤ $2.00
This inequality states that the variable "x" is less than or equal to $2.00.
2. The price of a gallon of gasoline varies from $1.099 to $1.399:
Let's define the variable "y" to represent the price of a gallon of gasoline. The given scenario suggests that the price is between $1.099 and $1.399. We can write this as an inequality:
$1.099 ≤ y ≤ $1.399
This inequality states that the variable "y" is greater than or equal to $1.099 and less than or equal to $1.399.
So, the inequality notation to describe the set of any numbers in these scenarios would be:
1. x ≤ $2.00
2. $1.099 ≤ y ≤ $1.399
