Jeff has 10 hot dogs. Half were eaten by his dog. He goes to the store and buys two more packages. Now Jeff has 21 hot dogs . How many were in each package?

Question

how many were in each package?

Answer 1

10 - 5 = 5       half were eaten

5 + 2x = 21    added 2 packages

2x = 16          subtract 5 form both sides

x = 8              divide both sides by 2

 

Each package has eight hot dogs.
