Amanda has saved $18.25. How much more does she need to save to buy a $45 pair of ice skates? Write and solve an equation. 

• 45 + 18.25 = x; $63.25
• 18.25 + x = 45; $26.75
• 45-18.25 = x; $26.75
• 18.25 + x = 45; $63.25

The speed limit on an Arizona highway is 75 miles per hour. Suppose a truck traveling at the speed limit drives 225 miles before taking a break. Write an equation to find the length of time the truck has traveled.

• 225/h = 75; h = 5
• 225 + h = 75; h = 150
• 225h = 75; h=1/3
• 75h = 225; h=3
