Answer:
Step-by-step explanation:
Umm well mean you just have to use like terms. start by doing any math until there are no parenthesis, and then you basically just use like terms to solve it. (like if you have 
then you use like terms) I would need specifics to be able to evaluate more, but I hope this helps!
Each bracelet was approximately 20.25
Here is my work:
67.50 - 27 = 40.5
40.5 divided by 2 = 20.25

Answer:
Yes
Step-by-step explanation:
Of course we can.
To solve this we are going to use the half life equation
Where:
is the initial sample
is the time in years
is the half life of the substance
is the remainder quantity after
years
From the problem we know that:
Lets replace those values in our equation to find
:
We can conclude that after 1600 years of radioactive decay, the mass of the 100-gram sample will be
91.7 grams.
Divide 83.524 by pi then take half of that answer .
the answer should be 13.29 or 13.3
