Alan paid $1.12 for a dozen eggs at his local grocery store. Determine the cost of 3 eggs
3(1.12/12) = ________
That would be $0.28, or 28 cents.
To determine the cost of 3 eggs, we can set up a proportion using the given information.
Since Alan paid $1.12 for a dozen eggs, we know that the cost of 1 dozen eggs is $1.12.
A dozen consists of 12 eggs, so the cost of 1 egg would be $1.12 divided by 12.
Cost of 1 egg = $1.12 / 12 = $0.0933 (rounded to four decimal places)
Now that we know the cost of 1 egg, we can find the cost of 3 eggs by multiplying the cost of 1 egg by 3.
Cost of 3 eggs = $0.0933 × 3 = $0.2799 (rounded to four decimal places)
Therefore, the cost of 3 eggs is approximately $0.28.
