To calculate Sally's annual wages, you first need to determine how many weeks she works in a year. Since she takes 2 weeks off for an unpaid vacation, she works for:
\[ 50 , \text{weeks} \]
Next, multiply the number of weeks she works by her weekly earnings:
\[ \text{Annual wages} = \text{Number of weeks worked} \times \text{Weekly earnings} \]
Substituting in the numbers:
\[ \text{Annual wages} = 50 , \text{weeks} \times $1,000 , \text{per week} = $50,000 \]
So, Sally's annual wages for the year amount to $50,000.
