"Using the given information, determine the cost of one no rechargeable alkaline battery; and compare with the cost of one rechargeable NiCad battery. *Assumption: The cost of the electricity to recharge the NiCad is negligible (about $0.01). NiCad batteries can be recharged (reused) 100 times. A 4 pack of AA NiCad rechargeable batteries cost $10.80. A 4 pack of AA alkaline non rechargeable batteries cost $3.69. Over the life of the battery, which battery is most cost effective? Group of answer choices The NiCad AA rechargeable battery The AA alkaline non rechargeable battery Both batteries cost are the same Batteries are independent of chemical composition and therefore does not impact consumer cost structures"

Over the life of the battery, the battery that is most cost-effective is:

The AA alkaline non rechargeable battery.

Explanation:

a) Data and Calculations:

Number of times that NiCad batteries can be recharged (reused) = 100 times

Cost of a 4 pack of AA NiCad rechargeable batteries = $10.80

Recharging cost = $1 ($0.01 * 100)

Total cost of AA NiCad rechargeable batteries = $11.80

Cost per use = $0.12 ($11.80/100)

Cost of a 4 pack of AA alkaline non rechargeable batteries = $3.69

Cost per use of AA alkaline non rechargeable batteries = $0.04 ($3.69/100)

b) The comparison and the resulting conclusions are based on the assumption that the non rechargeable and the rechargeable batteries enjoy equal useful life.  Therefore, the AA alkaline non rechargeable batteries are also used 100 times.
