Answer:
make fewer than 10 dresses per month
Step-by-step explanation:
Note she already has s fixed marginal of $600 per dress, which makes a total marginal cost of $6000 ($600*10) for the month higher than her revenue.
However, to make at least a profit, if she reduces the number of the dresses to maximum of 8, her total marginal cost would be $4800 (600*8), which would result in a profit of $200 ($5000-$200).
