Evarado paid $1.12 for a dozen eggs. Write and solve a proportion to determine the cost of the 3 eggs Evarado needs for a recipe.

$1.12 / 12 eggs = x / 3 eggs
Cross-multiply:
($1.12 times 3 eggs) = ('x' times 12 eggs)
3.36 dollar-eggs = 12x eggs
Divide each side by 12 eggs :
3.36 dollar-eggs / 12 eggs = x
x = 0.28 dollar

To determine the cost of the 3 eggs Evarado needs for a recipe, we can set up a proportion using the cost of a dozen eggs. Let x represent the cost of the 3 eggs. We know that $1.12 is the cost of a dozen eggs, so we can write the proportion as:
12 eggs = $1.12
3 eggs = x
To solve for x, we can cross multiply:
12 * x = 3 * $1.12
12x = $3.36
To isolate x, we divide both sides by 12:
x = $3.36 / 12
x = $0.28
Therefore, the cost of the 3 eggs Evarado needs for the recipe is $0.28.
