Question

Finley and Booker sold candles for a school fundraiser. Booker sold 3 times as many candles as Finley. Finley sold 12 less candles than Booker. If each candle gives the seller $5.75 in profit, how much profit does each person make? Please help me I am struggling with this

Answer 1

Booker: $103.50 profit

Finley: $34.50 profit

Explanation:

b = # of candles Booker sold

f = # of candles Finley sold

1) b = 3f

2) f = b - 12 substitute b=3f into this equation to get an expression all in terms of f, then solve for f

f = 3f - 12

-2f = -12

f = -12/2 = 6 now plug this into either equation and solve for b

b = 3(6) = 18

Booker: 18 candles x $5.75 profit/candle = $103.50 profit

Finley: 6 candles x $5.75 profit/candle = $34.50 profit
