Answer 1

3.49 for 8 candles

Explanation:

2.99/6=.49833

4.49/9=.49888

5.99/12=.49916

3.49/8=.43625

Answer 2

Unit rate is total price divided by quantity. This gives you the cost for 1 item.

Unit costs:

2.99 / 6 = 0.4983 each

4.49 / 9 = 0.4988 each

5.99 / 12 = 0.4991 each

3.49 / 8 = 0.4362 each

The Best Buy would be the one with the lowest unit price.

The Best Buy would be 3.49 for 8 candles.
