To determine how much 100mg of radon will decay in five days, we can substitute t = 5 in the formula P(t) = 100e^(-0.173t).
P(5) = 100e^(-0.173 * 5)
= 100e^(-0.865)
≈ 100 * 0.421
≈ 42.1
Rounding 42.1 to the nearest whole number, we get 42.
Therefore, approximately 42mg of radon will decay in five days.
