Answer :

To identify which of Tiffany's expenses are variable, we need to examine if the value for each category changes from month to month.

1. Rent:
- [tex]$\$[/tex]1,150.00[tex]$, $[/tex]\[tex]$1,150.00$[/tex], [tex]$\$[/tex]1,150.00[tex]$, $[/tex]\[tex]$1,150.00$[/tex], [tex]$\$[/tex]1,150.00[tex]$, $[/tex]\[tex]$1,150.00$[/tex]
- The rent remains constant each month. Thus, rent is not a variable expense.

2. Utility Bill:
- [tex]$\$[/tex]114.11[tex]$, $[/tex]\[tex]$118.98$[/tex], [tex]$\$[/tex]124.41[tex]$, $[/tex]\[tex]$105.30$[/tex], [tex]$\$[/tex]110.58[tex]$, $[/tex]\[tex]$129.86$[/tex]
- The utility bill values change from month to month. Therefore, the utility bill is a variable expense.

3. Car Loan Payment:
- [tex]$\$[/tex]377.00[tex]$, $[/tex]\[tex]$377.00$[/tex], [tex]$\$[/tex]377.00[tex]$, $[/tex]\[tex]$377.00$[/tex], [tex]$\$[/tex]377.00[tex]$, $[/tex]\[tex]$377.00$[/tex]
- The car loan payment remains consistent each month. Thus, car loan payment is not a variable expense.

4. Insurance Payment:
- [tex]$\$[/tex]91.50[tex]$, $[/tex]\[tex]$91.50$[/tex], [tex]$\$[/tex]91.50[tex]$, $[/tex]\[tex]$91.50$[/tex], [tex]$\$[/tex]91.50[tex]$, $[/tex]\[tex]$91.50$[/tex]
- The insurance payment does not change. Thus, insurance payment is not a variable expense.

5. Groceries:
- [tex]$\$[/tex]352.30[tex]$, $[/tex]\[tex]$329.63$[/tex], [tex]$\$[/tex]310.29[tex]$, $[/tex]\[tex]$328.69$[/tex], [tex]$\$[/tex]342.46[tex]$, $[/tex]\[tex]$304.93$[/tex]
- The amount spent on groceries varies each month. Thus, groceries is a variable expense.

6. Savings Account:
- [tex]$\$[/tex]150.00[tex]$, $[/tex]\[tex]$150.00$[/tex], [tex]$\$[/tex]150.00[tex]$, $[/tex]\[tex]$150.00$[/tex], [tex]$\$[/tex]150.00[tex]$, $[/tex]\[tex]$150.00$[/tex]
- The amount saved each month is the same. Thus, savings account is not a variable expense.

7. Clothing:
- [tex]$\$[/tex]105.67[tex]$, $[/tex]\[tex]$52.74$[/tex], [tex]$\$[/tex]0.00[tex]$, $[/tex]\[tex]$76.12$[/tex], [tex]$\$[/tex]23.90[tex]$, $[/tex]\[tex]$134.85$[/tex]
- The spending on clothing changes every month. Thus, clothing is a variable expense.

8. Fuel:
- [tex]$\$[/tex]112.50[tex]$, $[/tex]\[tex]$107.32$[/tex], [tex]$\$[/tex]109.24[tex]$, $[/tex]\[tex]$102.87$[/tex], [tex]$\$[/tex]117.46[tex]$, $[/tex]\[tex]$98.41$[/tex]
- The amount spent on fuel changes each month. Thus, fuel is a variable expense.

Therefore, the variable expenses from Tiffany's spreadsheet are utility bill, groceries, clothing, and fuel.
