Final answer:
Divide the total cost of $1.12 by the number of eggs in a dozen (12) to find the cost per egg, which is $0.09.
Step-by-step explanation:
The question requires us to find the cost of one egg when Everardo paid $1.12 for a dozen eggs. To do this, we need to understand that a dozen equals 12 units. Therefore, to determine the cost of one egg, we divide the total cost by the number of eggs in a dozen.
The calculation would be:
$1.12 ÷ 12 eggs = $0.0933 per egg
Considering the options provided, we must round to the nearest cent, which gives us an answer of $0.09 per egg, corresponding to option A.
