Answer:
The correct choices are 2,3,5
Step-by-step explanation:
We can write an exponential decay function for this problem
y= ab^x
where a is the initial value
b is 1 - decay rate
x is the time
y= 70000 (1-.5) ^x where x is the number of 4 hour periods
y = 70000 (.5)^x
The half life is every 4 hours
24 hours is 24/4 = 6
y = 70000 (.5)^6
y = 1093.75 at 24 hours
