Original price - discount = sales price
x - 0.3(x) = 63
0.7x = 63
x = 63/0.7
x = 90 <=== original price
![25.00/ 10= 2.50 \\ 2.50*1.5= 3.75 \\ 25.00+3.75= 28.75](https://tex.z-dn.net/?f=25.00%2F%2010%3D%202.50%0A%20%5C%5C%202.50%2A1.5%3D%203.75%20%5C%5C%2025.00%2B3.75%3D%2028.75)
As you've got 15%, the best thing to do is to find 10%, then multiply it by 1.5. Once you've found the tip, you add this onto the cost of the meal.
Therefore, the total cost of $25 meal with a 15% tip is $28.75
Hope this helps :)
