Brandy wants to buy a digital camera that costs $300. Suppose she saves $15 each week. In how many weeks will she have enough money for the camera? Use a bar diagram to solve arithmetically. Then use an equation to solve algebraically.
Bar Diagram:
Weeks: 1 2 3 4 5 6 7 8 9 10
Saved: 15 30 45 60 75 90 105 120 135 150
Answer: Brandy will have enough money for the camera in 10 weeks.
Equation:
15x = 300
x = 20
Answer: Brandy will have enough money for the camera in 20 weeks.
Too funny

posted both. Logically, at least one of them had to be wrong
