PROVE YOUR ANSWER.

Douglas gets an allowance of $5.00 every week and wants to save it to buy a bike that costs 200 dollars. Which equation shows how many weeks Douglas will take to save enough money to buy the bike?

• 5x = 200

• 200 − 5 = x

• 200 + 5 = x

• Divide both sides by 6.

• Multiply both sides by 6.

• Multiply both sides by 30.

• Subtract 6 from both sides.
