4 grams sample will be left after 1 year
Step-by-step explanation:
The decay function for percentage decay is given by:
[tex]y =a (1-r)^x[/tex]
Here,
a is the initial value
r is the rate
x is the number of time periods
Given
Initial value = 100 grams
Rate = 6% = 0.06
Time = 1 year = 52 weeks
Putting the values in the formula
[tex]y = 100 (1-0.06)^{52}\\y = 100(0.94)^{52}\\y = 4.00\ grams[/tex]
Hence,
4 grams sample will be left after 1 year
