Best ResponseYou've already chosen the best response.1You do something similar with the ozone one let me just leave the formula since amistre can help you with the concept\[N_t = N_0(1.46)^{t/7}\]

Best ResponseYou've already chosen the best response.07 days = 1/2x{0} + x{0} = x{n+1} x{1} = 100(1.5) = 150 x{2} = 150(1.5) = ......is that what i was missing last time the 1?

Best ResponseYou've already chosen the best response.0Ok, so the equation should look like 1300= 100(1.46)^(t/7).....right?

Best ResponseYou've already chosen the best response.0moving on, I should get to (log 13/log 1.46) = t/7.......right?

Best ResponseYou've already chosen the best response.1remidia, since I don't know what the answer choices are I cannot say this by 100%, but it takes exactly 7*ln13/ln1.46 days to reach 1300. Which means that if it is any less than that you still haven't reached 1300. so, if there, by any chance, were two solutions 47 days or 48 days, make sure to pick 48 days, ok ?
