Joe earns $25 per yard he mows in the summer.  If he also makes a one time amount of $100 for babysitting his brother, write an equation that can be used to determine the number of yards (y) he will need to mow to go to Italy for $3,100.  

• 25y - 100 = 3,100

• 3,100 - 100 = 25y

• 25y + 100 = 3,100

• 100y + 25 = 3,100
