If a dozen pencils cost $1.35, what is the unit cost?
1. $0.11
2. $1.23
3. $0.13
4. $4.29
To find the unit cost, we need to divide the total cost by the number of units.
The total cost is $1.35 and the number of units is 12.
$1.35 / 12 = $0.1125
Since we are dealing with money, we round this to the nearest cent.
The unit cost is therefore $0.11.
Therefore, the correct answer is option 1: $0.11.
