The start up cost to join eTunes music is $7.95 plus $0.95 per song downloaded.  Write a linear equation that could be used to find how many songs he downloaded.

• y = 0.95x + 7.95
• y = 7.95x + 0.95
• y = 0.95x - 7.95
• y = - 0.95x + 7.95

At a pet store, it costs $5 to wash a cat and $7.50 to wash a dog.  Last week, the store made $60 from washing cats and dogs. Write a linear equation that could be used to find how many cats and dogs were washed.

• -5x + 7.5y = 60
• 5x + 7.5x = 60
• 5x - 7.5y = 60
• 5x + 7.5y = 60
