Question

a warehouse store sells 5.5-ounce cans of tuna in packages of 6. a package of 6 cans costs $9.24. the store also sells 6.5-ounce cams of the same tuna in packages of 3 cans for $4.68. it also sells 3.5-ounce cans in packages of 4 cans for $4.48. which package has the lowest cost per ounce of tuna?

Answer 1

9.24 / (5.5 * 6) = 9.24 / 33 = 0.28 per oz

4.68 / (6.5 * 3) = 4.68 / 19.5 = 0.24 per oz

4.48 / (3.5 * 4) = 4.48 / 14 = 0.32 per oz

so the lowest cost is the 6.5 oz tuna in packs of 3 cans for 4.68

Answer 2

Second package costs the lowest.

Explanation:

A ware house sells tuna cans weighing = 5.5 ounce

It sells the cans of tuna in the package of 6.

Weight of 6 cans = 5.5×6 ounce

Cost of the 6 cans = $9.24

Therefore, cost of 1 tuna can =
`(9.24)/(5.5* 6)=0.28`per oz

Now weight of second type of tuna can = 6.5 ounce

Weight of 3 cans = 3×6.5 = 19.5 ounce

Cost of 3 tuna cans = $4.68

Cost of 1 tuna can =
`(4.68)/(19.5)`

= $0.24 per oz.

Similarly cost of third type of tuna can =
`(4.48)/(4* 3.5)`

= $0.32 per oz

Second package has the lowest cost per ounce of tuna.
