🤓 Based on our data, we think this question is relevant for Professor Mccaffrey's class at MDC.

A sample of a dish from an archaeological dig gave 18,500 disintegrations per gram of carbon per day. A 1.00 g sample of carbon from a modern source gave 22,080 disintegrations per day. If the decay constant of carbon-14 is 1.2 x 10^{-4} y^{-1}, what is the age of the dish?

a) 640 y

b) 8300 y

c) 68,000 y

d) 30,000 y

e) 1,500 y
