Solve Problems with One Step Equations

Javier has saved $55 toward the purchase of an IPOD. The IPOD costs $145. Which equation represents the amount Javier needs to save to by the IPOD?

• 55 + x = 145

• 145x = 55

• 55 - x = 145

• 145 (55) = x

In 2010, a tree was 8 feet tall. In 2011 the tree was 14 feet tall. Which equation would be used to find how many feet the tree grew?
