The initial count of a certain type of bacteria in a culture is 350. if the bacteria grows at the rate of 20% per hour, which function models the number of bacteria after t hours?

I think it is 350(1.2)^t because you take the starting amount (350) and then multiple it by the growth rate (which is 20%, but when added to 100 and the put into a decimal is 1.2) raised by the number of hours (t).
I hope this helps.
