If a dozen pencils cost $1.35, what is the unit cost?
A. $0.11
B. $1.23
C. $0.13
D. $4.29
To find the unit cost, we need to divide the total cost by the number of pencils.
Total cost: $1.35
Number of pencils: 12
Unit cost = Total cost ÷ Number of pencils
Unit cost = $1.35 ÷ 12
Unit cost = $0.1125
Rounded to the nearest cent, the unit cost is $0.11.
Therefore, the correct answer is A. $0.11.
