Answer:

Step-by-step explanation:
In this problem we have a exponential function of the form

where
f(x) is the remaining mass of the element in grams
x is the time in minutes
a is the initial value (y-intercept of the exponential function)
b is the base
r is the rate

In this problem we have

---> is negative because is a decay's rate

substitute
The exponential function is equal to

For x=15 minutes
substitute in the function


There are 112 days in 16 weeks because if you multiply 7 times 16 you get 112 days.
