T = F + V

Where:

T = Total Expenses
F = Fixed Expenses
V = Variable Expenses

Substituting Values

We can substitute the values of Jessie's fixed and total expenses into the equation to get:

$3,995.72 = 1,838.03 + V$

Solving for Variable Expenses

To find the value of Jessie's variable expenses, we can subtract her fixed expenses from her total expenses:

V = T - F = $3,995.72 - $1,838.03 = $2,157.69
