Hi, could someone give explanation and show me steps for this question, please? Thank you so much!

A boutique pays a monthly rent of $3,000 and hires an assistant at $1,500 per month. The clothes business is slowing due to online shopping. Currently, each dress is selling at $50 and the cost per dress is $17 plus a commission of $3 per dress. Calculate how manymorenumber of dresses above the breakeven number that the company needs to sell if the monthly target profit is $1,800.
