    Time: 0 -> 1 Bacteria Time: 1 -> 2 Bacteria Time: 2 -> 4 Bacteria so, in time x we have 2^x bacteria now, in time 8 (after 8 hours) we have 2^8 Bacteria, means 256! and in start we have 1, so after 8 hours we have 255 bacteria plus that one! the answer is 255

    @Mackenzie_Willa, you can answer the question by coming up with the equation for the given graph. Have you thought about what the equation for the graph might be?

    It's not about you posting a response, it's about your approach. We discussed this already.
