1. Percent applications project
By: Hunter P.

2. My ‘‘overpriced’’ receipt from Chick fil a
Kids meal = 3.99
8 count nugget meal = 5.79
Water = 0.04
Chicken sandwich = 6.39
All equals $16.21 without tax of course as my subtotal price. 

3. Now the math to find out my full cost
I gave them a 15% gratuity and you multiply $16.21 and $0.15 and you get $2.43 we need to find sales tax now
Multiply $16.21 and $.0825
You should get an answer of $1.33 then add that to $2.43 you should get an answer of $3.76 then add that to $16.21 you should get an answer of $19.97 that is your total cost

4. The three observations I made
That you use this in your everyday life. Use %s in businesses and cooking etc. Sales tax increases the cost of the regular product with out it, it would be much cheaper.

5. Formulas I used
I used a percent equation to solve this a=pxb Sales tax= $16.21x.15=$2.43 Tip+ $16.21x $1.33 Total cost= $16.21x$3.76=$19.97

6. That is all 
