Exponential Growth Word Problem

[PAULIE_RULES]

A certain Strepococcus strain of bacteria can grow from 60 to 900 in 150 minutes. Find k in the formula and write the growth equation. How do I find k????? And what does it mean to write the growth equation?

Thank you so much

Find k in the formula....

Which formula?

Sorry!

A(t) = A(0)e^kt

or if it makes it easier to read

At = A0 ekt

You've been given the two points (t, A) = (0, 60) and (t, A) = (150, 900). Plug the first one in, and solve for the value of A₀. Then plug the second one in, and use logs to solve for the value ot k.
