if 3 candles cost $16.50 how much do 5 candles cost

Question

If 3 candles cost $16.50 how much do 5 candles cost

 

 

Answer 1

We can set of a proportion.

 

 

The ratio of cost = the ratio of amount of candles.

 

16.50 / x = 3 / 5

 

 

Cross multiply.

 

3x = 5(16.50)

3x = 82.50

  x = 27.50

 

5 candles cost $27.50 

 

This makes sense because the more candles you buy, the more you pay for them.
