Radium-226 has a half life of 1660 years.How many years does it take a radium sample to decay to 55% of the original amount. Round to the nearest year.
Please help me set up this equation!

Please help me set up this equation!
here are some links:
Effective half-life - Wikipedia, the free encyclopedia
Radioactive decay - Wikipedia, the free encyclopedia
The equation you want is
(equation 1)
whereis the original amount of material present.
is the time in the same units as the half-life,
is the half-life.
in your case
Divide both sides of equation 1 by. Enter the data you have and solve for t.
I got a negative answer... I I got it, you missed a 'minus' sign in front of your power of two Perito...
What's happening to you today? Tired?
We can easily find k, the constant of proportionately, from the formula for half-life:
Since we are given the half-life is 1660, all we need to do is solve for k.
Now we can sub this into the equation and solve for t:
Solve for t.
Can u put this in simple terms for me
