To solve this problem you must apply the proccedure shown below:
1. Based on the information given in the problem above, you can write the following expression, where [tex] x [/tex] is the total amount you will collect from your sponsor at the end of the walk-a-thon:
[tex] x=5+2(20)\\ x=5+40\\ x=45dollars [/tex]
2. Therefore, as you can see, the answer is: if you walk for 20 miles, the total amount you will collect from your sponsor at the end of the walk-a-thon is [tex] 45dollars [/tex]
Amount the sponsor committed to give flat for participation in the walk-a-thon is $5.
This means that this amount is a constant.
Now for every mile amount that can be won is $2.
Now for x miles the amount that can be won is two times x = 2x dollars.
So let us make an equation for this question.
Total amount A is given by:
[tex] A = 5+2x [/tex]
x is number of miles.
In our question we have to find amount won in case of 20 miles.
So plugging x as 20 in the equation,
[tex] A = 5+2(20) [/tex]
Amount = 45 dollars.
Answer: The total amount that I will collect at the end of walk-a-thonfrom the sponsor is $45.
