I was stuck on this problem too but I finally figured it out. One major hint was let x= the number of DAYS. So taking both of the growth rates into account the solution is this.

Colby:
He starts with 50 bacteria so that is your a value or y intercept. Keeping in mind x is the number of days you divide the number of hours in a day (24) by the time it takes to double (2 hours) and get 12. So the equation for Colby is y=50*2^12x

Jaquan:

You do the same thing except with Jaquan's part of the equation and divide 24 by 3 to get 8. The solution for Jaquan is y=50*2^8x

Answer: -7/5

​

Step-by-step explanation:

x = - 5cm^2 - 7m^2 + 35/ m (5c - 7), C = (cross out the equal sign) 7/5 and m = (cross out the equal sign) 0 and n = -7/5
