Mark has an egg farm. His farm supplies one store with 5 dozen eggs and another store with 30 eggs each day. How many eggs does he supply these two stores in a week?
##Solution## Since a dozen is equal to 12, then Mark's egg farm supplies one store with 5 x 12 = <<5*12=60>>60 eggs each day.
It supplies the two stores with a total of 60 + 30 = <<60+30=90>>90 eggs each day.
Therefore, the egg farm supplies the two stores with 90 x 7 = <<90*7=630>>630 eggs in a week.
