So, 0.5^5 is 0.03125
multiply that by 125 and get your answer.
*3.90625* (4)
just saying, I got the 0.5^5 thing because 5 is the number of half-lives (x) and 0.5 is the rate of loss (or whatever its called).
If it were to gain, you would put 1.5
Set up multiplication of ratios so that they cancel out units that you do not need in your final answer...
5lb($4.20/2lb)=$10.50
I don’t have the time to do this, but there is a app called Socratic where you can take a pic of your homework and it searches everything on google.
That’s how I got Brainly
