Whole numbers are numbers without decimal points greater than 0.
The set of whole numbers is:

In the introductory part of this solution, I stated that:
- Whole numbers do not have decimal point
- The smallest whole number is 0
This means that the following numbers are whole numbers:
1, 9, 10, 67
While the following numbers are not:
-1, 9.0, 1.0, -67
Let W be the set of whole numbers; the set is:

The dots after 4 means the set still continues

Step-by-step explanation:
Answer:
Each hotdog costs $1.65
Each juice drink costs $1.05
Step-by-step explanation:
Let's begin by letting
represent the number of hot dogs and
the number of juice drinks.
The Baxter family bought 6 hot dogs and 4 juices for $14.10.

The Farley family bought 3 hot dogs and 4 juices for $9.15.

Now, we subtract these equations.

Since
has reversed coefficients, it gets eliminated. Now solve for x.



NOW, we find y by substituting x with 1.65 (in either equation).
We'll use the first equation.




= 1.65
= 1.05
represents hotdogs and
represents juice drinks.
Therefore, each hotdog costs $1.65 and each juice drink costs $1.05.
