Asked by Thelma

instead of buying packages of 20 batteries for $7.00 to power his video game controllers, Nathaniel decides to buy 4 rechargeable batteries and a charger for $15.39. How many times does he need to use the rechargeable batteries to make them a better value?
Answered by Ms. Sue
That depends upon how long the nonrechargeable batteries last.
