the learning curve describes the rate at which a person learns certain tasks. If a person sets a goal of typing N words per minute (wpm), the length of time t (in days) to achieve this goal is given by

Question

t= -62.5 IN (1- N over 80)
according to this formula, what is the maximum number of words per minute? Round the answer to the nearest whole number.
B) solve for N. N=

Answer 1

I suspect that this is a log question and your IN is actually ln ( the natural logarithm)

so let's try:
t = -62.5 ln(1 - N/80)
or is it
t = -62.5 ln( (1-N)/80)
