We have been given an equation 
. We are asked to solve the equation for t.
First of all, we will divide both sides of equation by a.
Now we will take natural log on both sides.
Using natural log property 
, we will get:
We know that 
, so we will get:
Now we will divide both sides by c as:
Therefore, our solution would be .
Answer:
She rode her bike 20 miles... I believe this may be a trick question.
Step-by-step explanation:
Let's break down this problem...
If she is going at a rate of 5 miles per hour while walking than the maximum she could have walked in 5 hours is 25 miles.
If Angela rode her bike for 20 miles, and the got off her bike and walked "<em>the rest of the way</em>" then she should have walked 50 miles. However as we already know her rate is 5 miles per hour while walking, and therefore could only have covered half that distance in 5 hours.
Is this a multiple choice question? Is there any misssing informaation?
How you would set this up would be as follows:
(50*30)+4,596*.03
The 50*30 is her earning $50 a day for 30 days. Then to find her commission earnings you multiply her sales of 4,596 times the commission rate of 3%(when you move the decimal place you get .03)
Add them together and you get her total amount earned of $1,637.88
Hope this helped!
