Question

A. which is the better value a 12 ounce jar of honey for $2.25 or an 18 ounce jar of honey for $3.24?

b. the supermarket displays the unit price for the 12 ounce jar in terms of cost per ounce, but displays the unit price for the 18 ounce jar in terms of cost per quart. Assuming 32 ounces in a quart, what are the unit prices, to the nearest cent, given by the supermarket?

c.) based on your work in parts a and b does the better value always have the lower displayed unit price? Explain your answer.

Answer 1

A. The 18-ounce jar is a better bargain. Just calculate what 6 ounces of each container will cost.
B. The unit price for the 12-ounce jar is $0.1875 per ounce, while the unit price for the 18-ounce jar is $6.48 per quart.
C. Well, yes. The price per ounce for the 18-ounce jar is $0.18 per ounce. The only reason you would think not is the illusion of different increments used for the unit price.

Answer 2

A:

12 ounce jar of honey for $2.25

1 ounce =
`(2.25)/(12)` = $0.1875

18 ounce jar of honey for $3.24

1 ounce =
`(3.24)/(18)` = $0.18

Hence, 12 ounce jar of honey for $2.25 is better.

B:

There are 32 ounces in 1 quart.

Cost of 1 ounce = $0.18

So, cost of 32 ounce =
`32*0.18=5.76`

Hence , it is $5.76 per quart.

C:

Yes because if you see something in quarts, it will have a larger price as compared to ounce.

And daily use items are usually not measured in quarts.
