Question

You want to buy some rice. An 8​-ounce package costs ​$3.04. A 14​-ounce package costs ​$5.04. Upper A 26​-ounce package costs ​$9.62. Which package is the best​ buy?

Answer 1

An 14​-ounce rice package costs ​$5.04 is the best​ buy. This is because we have to pay less cost of rice per ounce in comparison with other packages.

Explanation:

1) An 8​-ounce rice package costs ​$3.04

Cost of an ounce of rice =
`(\$3.04)/(8)=\$0.38`

2) An 14​-ounce rice package costs ​$5.04

Cost of an ounce of rice =
`(\$5.04)/(14)=\$0.36`

3) An 26​-ounce rice package costs ​$9.62

Cost of an ounce of rice =
`(\$9.62)/(26)=\$0.37`

$0.36 per ounce <$0.37 per ounce <$0.38 per ounce

An 14​-ounce rice package costs ​$5.04 is the best​ buy. This is because we have to pay less cost of rice per ounce in comparison with other packages.
