If 52 bacterial colonies grow on a nutrient agar plate inoculated with on mL...

If 52 bacterial colonies grow on a nutrient agar plate inoculated with on mL of a 1 :10000 dilution of 1.0 g hamburger, how many bacteria are in the original hamburger sample?

Assume that you inoculate potato salad wih 1.0x10^5 bacterial cells and stored it at room temperature. After three hours there are 1.6x10^6 cells. How many generations did the cells go through?
