Question 1174355: 14. Molly has a business making candles. Her
business costs are $200 plus $0.70 per
candle made. She charges her customers
$3.50 for each candle. If she sells all of the
candles she makes, how many candles sold
would allow her to make a profit?

You can put this solution on YOUR website!
200+0.70x=3.50x, cost on the left, revenue on the right
solve for x
2.80x=$200
x=71.43 candles or 72 or more candles would cause her to make a profit.
-
alternative way is she makes $2.80 on each candle sold, and divide that into 200.
