Mandy is playing a game on her phone where the number of obstacles she has to avoid triples each round. If she is currently on a round with 15 obstacles, in how many rounds will there be 405 obstacles to navigate? obstacles

Let’s break it down! If the number of obstacles triples each round, we can represent the number of obstacles in each round as follows: - Round 1: 15 obstacles - Round 2: \(15 \times 3 = 45\) - Round 3: \(15 \times 3^2 = 135\) - Round 4: \(15 \times 3^3 = 405\) So, it will take Mandy just 3 additional rounds to reach the point where there are 405 obstacles! Get ready to dodge like a pro! Now, if Mandy keeps on playing past this point, she’ll find herself facing even more challenges, as the number of obstacles will keep multiplying. In Round 5, she will encounter a whopping 1,215 obstacles – that's a serious test of reflexes! Play smart and stay focused!
