SOLUTION: The strontium-90 in a nuclear reactor decays continuously. If 200 mg is present initially, the amount present after t years is given by A(t)=200e^-0.0248t. Find, to nearest hundred

Question 598559: The strontium-90 in a nuclear reactor decays continuously. If 200 mg is present initially, the amount present after t years is given by A(t)=200e^-0.0248t. Find, to nearest hundredth, the amount letft after 50 years.
I really could use some help with this word problem. I would greatly appreciate your help and I thank you.

The strontium-90 in a nuclear reactor decays continuously.
If 200 mg is present initially, the amount present after t years is given by A(t) = 200e^-0.0248t. Find, to nearest hundredth, the amount left after 50 years.
:
50 yrs means t = 50
A =
:
A =
A = 200 * .289384
A = 57.88 mg after 50 yrs
