Maria is playing a video game. She earns 15 points when she completes Level 1. Each time she completes a level, she earns twice as many points as the previous level.

Question

How many points will Maria earn when she completes Level 8?

Answer 1

Maria earns 15 * 2 = <<15*2=30>>30 points when she completes Level 2.
When she completes Level 3, she earns 30 * 2 = <<30*2=60>>60 points.
When she completes Level 4, she earns 60 * 2 = <<60*2=120>>120 points.
When she completes Level 5, she earns 120 * 2 = <<120*2=240>>240 points.
When she completes Level 6, she earns 240 * 2 = <<240*2=480>>480 points.
When she completes Level 7, she earns 480 * 2 = <<480*2=960>>960 points.
Therefore, when Maria completes Level 8 she will earn 960 * 2 = <<960*2=1920>>1920 points. Answer: \boxed{1920}.
