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

[tex]\frac{115}{100}x=29.90\\1.15x=29.90[/tex]

Dividing both sides by 1.15

[tex]\frac{1.15x}{1.15}=\frac{29.90}{1.15}\\x=26[/tex]

The price is $26 before tip.
