Costco sells extra large eggs for $6.39 per two dozen. How much does each egg cost?

Question

At this price per egg, if James eats ten eggs per week, how much will he have spent on eggs in one year? (Hint: There are 52 weeks in one year)

Answer 1

First is the cost per egg:

 

2 dozen = 24

 

$6.39/24 eggs = $0.266/egg

 

10 eggs per week and 52 weeks a year means:

 

10*52 = 520 eggs per year

 

Price = 520*0.266 = $138.45/yr
