Answer:
The unit price of a 2-pack of batteries, rounded to the nearest cent, is $1.10.
Explanation:
The concept used in this question is the concept of "unit price."
The unit price refers to the price of a single unit or item of a product.
It is calculated by dividing the total cost of a pack or quantity of items by the number of units in that pack or quantity.
To find the unit price of a 2-pack of batteries, we need to divide the total cost by the number of units in the pack.
In this case, the total cost is $2.19 and the pack contains 2 batteries.
To find the unit price, we divide the total cost by the number of units:
$2.19 / 2 = $1.095
Rounded to the nearest cent, the unit price is $1.10.
Thus,
The unit price of a 2-pack of batteries, rounded to the nearest cent, is $1.10.
