Colby and jaquan are growing bacteria in an experiment in a laboratory. colby starts with 50 bacteria in his culture and the number of bacteria doubles every 2 hours. jaquan start with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. ( * equals x in this case ) colby’s experiment follows the model: ⓐ y = 50 • 2* ⓑ y = 50 • 2⁸* ⓒ y = 50 • 2¹²* jaquan’s experiment follows the model: ⓐ y = 80 • 2* ⓑ y = 80 • 2⁸* ⓒ y = 80 • 2¹²*
