Problema Solution
You make candles and sell them for 15 dollars each. The materials to make up 20 candles cost 20 dollars. How many candles must you sell to have a profit 85 dollars after expenses?
Answer provided by our tutors
let
x = the number of candles to sell to make profit of 85 dollars
the profit out of 20 candles is: 20*15 - 20 = 300 - 20 = $280
the profit out of 1 candle is: 280/20 = $14
the profit out of x candles is:x *14 = 85
x = 85/14
x = 6
by selling 6 candles the profit is 6*14 = $84
by selling 7 candles the profit is 7*14 = $98
to make a profit of at least $85 i must sell at least 7 candles.
