A= pe^rt

can you me solve for t?
i've tried using logs to isolate it, but i'm not good with logs and i couldn't figure it out.

That is the formula for solving for continuously compound interest.
You want to solve for time "t".
A = Pe^rt
Dividing both sides by "P"
(A / P) = e^r*t
Taking NATURAL LOGS of both sides:
(the natural log of "e" is 1)
ln (A / P) = ln (e^r*t)
ln (A / P) = r*t*1
ln (A / P) = rate * time
Time = ln (A / P) ÷ rate

1/10 of 2000 is 200 pounds. so 200 pounds of cheese

i guess you mean 100 times more lettuce than beef so that would be 200,000 pounds of lettuce

200+200,000=200,200 final answer
