Question

A warehouse store sells 3.5-ounce cans of tuna in packages of 8. A package of 8 cans costs $9.52. The store also sells 4.5-ounce cans of the same tuna in packages of 3. A package of 3 cans costs $4.86. The store sells 5.5-ounce cans in packages of 6 cans for $9.90. Which package is the best buy?

Answer 1

The 5.5-ounce cans in packages of 6 cans is the best buy, as it costs the least per ounce.

Answer 2

To determine which package is the best buy, we need to calculate the price per ounce for each package option.

For the package of 8 cans of 3.5-ounce tuna priced at $9.52:
- Divide the total price by the total number of ounces: $9.52 / (8 cans * 3.5 ounces per can) = $9.52 / 28 ounces = approximately $0.34 per ounce.

For the package of 3 cans of 4.5-ounce tuna priced at $4.86:
- Divide the total price by the total number of ounces: $4.86 / (3 cans * 4.5 ounces per can) = $4.86 / 13.5 ounces = approximately $0.36 per ounce.

For the package of 6 cans of 5.5-ounce tuna priced at $9.90:
- Divide the total price by the total number of ounces: $9.90 / (6 cans * 5.5 ounces per can) = $9.90 / 33 ounces = approximately $0.30 per ounce.

Comparing these prices per ounce, we can see that the package of 6 cans of 5.5-ounce tuna for $9.90 offers the best value, as it has the lowest price per ounce. Hence, this package is the best buy.

Answer 3

To determine which package is the best buy, we need to calculate the cost per ounce for each package.

For the 3.5-ounce cans sold in packages of 8, the price per package is $9.52. Therefore, the cost per ounce can be calculated as follows:

Cost per ounce = Price per package / (Number of cans per package * Ounce per can)
Cost per ounce = $9.52 / (8 * 3.5)
Cost per ounce = $9.52 / 28
Cost per ounce = $0.34

For the 4.5-ounce cans sold in packages of 3, the price per package is $4.86. Calculating the cost per ounce:

Cost per ounce = Price per package / (Number of cans per package * Ounce per can)
Cost per ounce = $4.86 / (3 * 4.5)
Cost per ounce = $4.86 / 13.5
Cost per ounce = $0.36

Finally, for the 5.5-ounce cans sold in packages of 6, priced at $9.90, the cost per ounce can be calculated as:

Cost per ounce = Price per package / (Number of cans per package * Ounce per can)
Cost per ounce = $9.90 / (6 * 5.5)
Cost per ounce = $9.90 / 33
Cost per ounce = $0.30

Based on the calculations, the package of 5.5-ounce cans is the best buy as it has the lowest cost per ounce at $0.30.
