The price is $26 before tip.
Step-by-step explanation:
Given,
Total bill including tip = $29.90
Let,
x be the amount before tip.
The bill before tip = 100%
Tip = 15%
Total bill = (100+15)% = 115%
Now,
115% of x = 29.90
![\frac{115}{100}x=29.90\\1.15x=29.90](https://tex.z-dn.net/?f=%5Cfrac%7B115%7D%7B100%7Dx%3D29.90%5C%5C1.15x%3D29.90)
Dividing both sides by 1.15
![\frac{1.15x}{1.15}=\frac{29.90}{1.15}\\x=26](https://tex.z-dn.net/?f=%5Cfrac%7B1.15x%7D%7B1.15%7D%3D%5Cfrac%7B29.90%7D%7B1.15%7D%5C%5Cx%3D26)
The price is $26 before tip.
