First, find the price of the table after the sale, so
600 x .3 = 180
600 - 180 = 420
Next, find the sales tax
420 x .08 = 33.6
420 + 33.6 = 453.6
Finally, add the shipping
453.6 + 7.5 = $461.1
20& 10/35 - 26/35
19& 16/35 simplified to it's fullest.
Note that 8.00 = (2.00)^3, that implies that a decay to 1/8.00 means that the Carbon-14 has passed 3 half-life. (1 to decay to 1/2, other to decay to 1/4, and other to decay to 1/8). And, three half-life is 3 * 5730 years = 17,920 years. So,<span> the answer is that the plant was alive 17,920 years.</span>
