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


Step-by-step explanation:
it is 1 - 6.9/100 =0.931
