Well, i guess i just have to stick to 49.5, thanks for answering, and yeah bob it's serious global warming, this is a significant increase in temperature, but it is not enough to cause immediate death for most people. However, such a significant increase in temperature would have severe consequences for the environment and the planet, including more frequent and intense heat waves, droughts, wildfires, and other extreme weather events. It could also have negative impacts on agriculture, biodiversity, and human health, among other things. Therefore, it is important to take action to address climate change and reduce greenhouse gas emissions to prevent such a scenario from happening.

Bob thank you so much!!, the answer was from the option.1 method where you said work back to find markup (cost = 15600 * 100/107 then markup = cost price) and double this also this question was from
