3-41.

At the annual dog show, Chantel noticed that there were three more Scotties than Schnauzers. She also realized that the number of Wirehaired Terriers was five less than twice the number of Schnauzers. If there were dogs in all (counting Schnauzers, Scotties, and Wirehaired Terriers), how many Schnauzers were there? Write and solve an equation. 

Try organizing your work in a table. Test some values to help decide what your equation should be.

Schnauzers

Scotties

Terriers

Total

Using your table, write algebraic expressions for the number of each dog. Using that information, write an equation and solve.
