Answer:
<em>945 minutes.</em>
Step-by-step explanation:
<em>10% = 0,1</em>
<em>450 + 450 · 0,1 = 495 (minutes) - Oliver will read next month.</em>
<em>450 + 495 = 945 (minutes) - he read in all during the two months.</em>
We need the half-life of C-14 which is 5,730 years.
Now, we will need a half-life equation:
elapsed time = half-life * log (bgng amt / ending amt) / log 2
We'll say beginning amount = 100 and ending amount = 41
elapsed time = 5,730 * log (100/41) / log 2
elapsed time = 5,730 * log (

) / 0.30102999566
elapsed time = 5,730 * 0.38721614327 / 0.30102999566
