Answer:
Step-by-step explanation:
<u>If I got it right, we have:</u>
- Formula Pf = P0*e^(rt)
- Pf = 75709
- P0 = 1349
- r = 25% = 0.25
- t = ?
<u>Substitute the given values and solve for t:</u>
- 75709 = 1349*e^(0.25t)
- e^(0.25t) = 75709/1349
- e^(0.25t) = 56.1223
- ln e^(0.25t) = ln 56.1223
- 0.25t = 4.03
- t = 4.03/0.25
- t = 16.12 hr
I guess your question is
<span>Sean read 15 of a book in 112 hours. How long will it take Sean to read 12 of this book?
