Situation: Find the age of the skull to the nearest year.
A hiker in Africa discovers a skull that
contains 63% of its original amount of C
14.
N = Noe
10
No = inital amount of C-14 (at time
t=0
N = amount of C++ at time
*+0.0001
t = time, in years

t = 6162  years

Step-by-step explanation:

Apparently you are asked to use the constant k = 0.0001 instead of the most common 0.00012. We'll answer the problem using such number you typed, but make sure that there is no omission in your typing.

The equation to use is that for carbon decay:

If the skull contains 54% of its original amount of C14, then that means that :

we use this to solve for the time (t) in our equation:

which rounded to the nearest year as requested gives :

t = 6162  years

answer: 1,380

step-by-step explanation:

1: you turn %15 into a decimal by moving the decimal point two places to the left.

2: and then you multiply .15 by 1,200 , which will get you 180.00

3: from there you will add 180 to 1,200

4: which will get you 1,380

hope it *im kind of slow so idk if my answer is right*

40% off the regular price is the correct answer.
