If one roll of masking tape costs $1.15, how many rolls can Emma buy  with $5.75?

• x = 1.15/ 5.75

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

• 55 + x = 145
• 145x = 55
• 55 - x = 145
• 145 (55) = x

• subtract both sides by 9

• add both sides by 9

• multiply both sides by 9

• divide both sides by 9
