What is Division?

The division is one of the four fundamental arithmetic operations, which tells us how the numbers are combined to form a new one.

To know which package is best, you need to get the value of a single battery for each battery. Therefore, the price of each battery in a pack is,

Cost of a battery in pack A = $8/3 = $2.667

Cost of a battery in pack B = $8/5 = $1.6

Cost of a battery in pack C = $24/12 = $2

Cost of a battery in pack D = $24/14 = $1.71

As it can be seen that the cost of a single battery is least in pack B. Therefore, the best deal package offer is 5 for $8. Hence, the correct option is B.
