980=75(1-75e^(-.07t) find t
Do I divide 75 from each side to give me
980/75=1-75e^(.07t)
How do I bring the 1-75 to the other side now. The book I have on explaining this sucks big time.
Any clue?
Ok I came up with something?
now I divide both sides by 1-75 which gives me
(980/75)/1-75 = e^ -.07t
Then I multiply both sides by Ln which gives me
ln(980/75)/(1-75) = -.07t
then just divide again by -0.07 to isolate t.
Now if it makes sense not sure.
I got an answer of 0.9252???
