Find unit cost if a store sells a dozen eggs for $1.99

The unit cost is $ 0.1658

Step-by-step explanation:

1 dozen = 12

We can simply use proportion to solve this problem;

Let x =the cost of 1 egg

12 eggs =  $1.99

1 egg      =    x

Cross-multiply

12x = $1.99

Divide both-side of the equation by 12 to get the value of x

12x/12 = $1.99/12

(At the left-hand side of the equation, the 12 on the numerator will divide the 12 on the denominator leaving us with just x, while at the right-hand side of the equation, 1.99 will be divided by 12)

x = $ 1.99/12

x = $ 0.1658

Therefore the unit cost of an egg is $ 0.1658
