4π = π × r²
r² = 4
r = 2
171 dollar because 1170 divde by 19.5 is 60 times 2.85 is 171
Answer
Exponential function is in the form of :
.....[1]
where a is the initial amount and r is the growth rate and (1+r) is the growth factor.
Given the function: 
On comparing with equation [1] we have;
Initial amount(a) = 12
1+r = 1.05
Subtract 1 from both sides we get;
or 5%
Growth (r) = 0.05 or 5%
Now, evaluate the function for t = 5 we have;
Substitute the value of t=5 in the given function we have;


Therefore, the value of function when t=5 to the nearest tenth is 15.3
