Answer:
Talking 65 minutes, $ 6.50 must be paid.
Step-by-step explanation:
Since your cell phone plan is by the minute, and each minute of use cost $ 0.10, to create a relation that represents the amount spent, A, per minute, m, of call time, and then use the relation to find the amount spent if you talk 65 minutes, the following calculations must be performed:
0.10 x M = A
0.10 x 65 = A
6.50 = A
Thus, talking 65 minutes, $ 6.50 must be paid.

Answer:
16.34 hours 
Step-by-step explanation:
According to the given information we can see that the case is of exponential growth
Hence, we will use the formula

Here A =800 is the amount that is needed to reach
P is the initial amount that is 500 
We have to find the time it will take to reach 800 that is we need to find t
On substituting the values in the formula we get

On simplification we get

Taking log on both sides we get

using 
And 

Now substituting values of log 8=0.903, log 5=0.698 and log 2=0.301 we get
