Given:
Price paid including tax: $37.48
sales tax = 5%
This means that $37.48 is equivalent to 105%
To get the value of the 100% or its original price, we divide the price paid by its percentage rate
$37.48 ÷ 1.05 = $35.70 value of the original price
$35.70 * 5% =  $1.78  value of sales tax
$35.70 + 1.78 = $37.48
        
                    
             
        
        
        
The interval for the function to be negative will be (-∞<x<-7).
<h3>What is a function?</h3>
A function in mathematics set up a relatioship between the dependent variable and independent variable. on changing the value of the independent variable the value of the dependent variable also changes.
Here we have a function:-
g(x) = ∛(x+6)
If we put the value of x lesser than 6 in the function we will always get a negative value so the interval will be:-
 (-∞<x<-7).
Therefore interval for the function to be negative will be (-∞<x<-7).
