Question

Josephine started a business selling cosmetics. She spent $4500 to obtain her merchandise, and it costs her $200 per week for general expenses. She earned $550 per week in sales. What is the minimum number of weeks it will take for Josephine to make a profit?

Answer 1

She spent 4500, so that's what she needs to go over.
it costs her 200 a week, so -200x where x = weeks
earns 550 a week, so +550x.

So now you write an equation, actually an inequality, because she needs to make more than 4500.
4500<550x+200x
Solve for x.
