DerKrebs [107]

Answer: $18

Step-by-step explanation:

Let x= Pretax price of the meal.

Given: Sales tax = 8%

Tip percent = 20%

As per given ,

Amount spent = ( Pretax price) + (Sales tax )  of (Pretax price) + (Tip percent)of (Pretax price)

=  x+ 8% of x +  20% of x

= x +0.08+0.20x

= 1.28x

∵ Amount spent =  $23.04

So,

1.28x=23.04\\\\\Rightarrow\ x=\dfrac{23.04}{1.28}\\\\\Rightarrow\ x=18

Hence, the pretax price of the meal= $18.
