To calculate the Maisel family's monthly income, we need to find out Miriam's monthly earnings based on her weekly paycheck.
Miriam earns $250 per week. Since there are typically 4 weeks in a month, we can calculate her monthly income as follows:
\[ 250 , \text{(per week)} \times 4 , \text{(weeks)} = 1,000 , \text{(monthly)} \]
Now, we add Joel's monthly income to Miriam's monthly income:
\[ 4,000 , \text{(Joel's monthly income)} + 1,000 , \text{(Miriam's monthly income)} = 5,000 \]
Therefore, the Maisel family’s monthly income is $5,000.
