18. Lucy is growing bacteria in a petri dish. She starts with 50 bacterial cells and notices after one hour she has 80 cells. After two hours, she has 128 cells. What is the exponential equation that determines how many bacterial cells are in the dish for any given hour? 50 - 1.6* O y = 1.6 - 50* y = 128 - 50* y = 50 +1.6z
