One of the byproducts of nuclear power generation is Uranium-233. Uranium is decaying at a constant 57% rate per day. If 3,820 pounds are produced from a power plant, what will the amount be in 15 days? 0.0739 19,737,001.91 19,737,001 0.739

Given that the decay rate of the uranium is given to be 57%, this means that on the second day only 43% of the Uranium-233 will be left. The equation therefore, that will allow us to answer the question is that,

A (t) = A (0) (1 - r) ^n

where A (t) is the amount after n days, A (0) is the original amount, r is the decimal equivalent of the rate and n is the number of days. Substituting the known values,

A (t) = (3,820 pounds) * (1-0.57) ^15

A (t) = 0.0121 pounds

This is unfortunately not found in the choices.
