Given:
Cost of meal = $25.00
Discount = $2.00
Sales tax = 7%
Tip = 15%
Let's find the total bill including the tax and the tip.
First find the cost of the meal after discount.
Cost after discount = $25.00 - $2.00 = $23.00
To find the discount percent, we have:
![\begin{gathered} \text{ Discount percent = }(2.00)/(25.00)\ast(100)/(1) \\ \\ \text{ Discount percent = }0.08\ast100=\text{ 8\%} \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/1agmga6jp8aarwhqehhn2cjuptg2lq6672.png)
The discount percent is 8%
The total bill after discount which includes the sales tax and tip is:
![\begin{gathered} Total=23(1+0.07+0.15) \\ \\ Total=23(1.22) \\ \\ =28.06 \end{gathered}](https://img.qammunity.org/2023/formulas/mathematics/college/acfrjuaulpy7rtqj3hhtv25xszi71jr2jl.png)
Therefore, the total bill including the tax and the tip after the discount is $28.06
ANSWER:
Discount percent = 8%
Total bill = $28.06
