9. A micro-biologist collected data on the population of the cancer cells in the sample. She determined that the cells were decreasing at a rate of 40% per hour once the chemo treatment was applied. She estimated there to be 2000 at the beginning of the experiment, write an equation that will model how the cells are declining that could then be used to find out how long before there are fewer than 10 cancer cells left.
