The Right Choice
Tom is choosing between two brands of AA batteries for his pocket flashlight. A package of two Brand A-Super batteries costs $4.99, and a package of two Brand B-Cool batteries costs $3.29. The runtime of the A-Super package is 2.5 hours. The runtime of the B-Cool package is 100 minutes.
Which should Tom buy?
Solution and explanation:
There isn't a correct answer here, but B-Cool is a less expensive choice.
2 packages of A-Super cost $9.98 and have a runtime of 5 hours or 300 minutes.
Three packages of B-Cool cost $9.89 and provide the same runtime
B-Cool is in this comparison cheaper assuming that Tom has the money to invest in 3 packages of B-Cool.
