To calculate your gross monthly pay from your gross weekly earnings, you can multiply your weekly earnings by the number of weeks in a month (approximately 4.33 weeks, since there are about 52 weeks in a year).
Here's the calculation:
\[ \text{Gross monthly pay} = \text{Gross weekly earnings} \times 4.33 \]
\[ \text{Gross monthly pay} = 289 \times 4.33 \approx 1,252.37 \]
The closest option to this calculation is $1,252.33.
