The parent volunteers made 120 snow cones in 5 hours. the student council made 100 snow cones in 4 hours. who made more snow cones per hour?

answer with supporting work:

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 starts with 80 of a different type of bacteria that doubles every 3 hours. let x equal number of days. colbys experiment follows the model: a.) y=50*2^x b.) y=50*2^8x c.) y=50*2^12x jaquans experiment follows the model: a.)80*2^x b.)80*2^8x c.)80*2^12x

Which is the focus of a parabola with equation y2=4x
