Decide which of the two given prices is the better deal and why. You can buy shampoo in a 6 ounce bottle for $2.49 or in a 14 ounce bottle for $9.79. What is the cost per ounce for each bottle?

Respuesta :

The cost per ounce of the first bottle is $0.415 and the second bottle is $0.699.

The first bottle has the better deal because if you were to have 14 ounces of the first type of shampoo, it would only cost $5.81

Cost per ounce is:

  • $0.42 per ounce for the 6 ounce bottle
  • $0.70 per ounce for the 14 ounce bottle

To find the cost per ounce for each bottle, use the formula:

= Total cost / number of ounces

6 ounce bottle:

= 2.49 / 6

= $0.42 per ounce

14 ounce bottle:

= 9.79 / 14

= $0.70 per ounce

The 6 ounce bottle is therefore the better deal.
