Answer:
The amount of sales tax was $6.81
Step-by-step explanation:
The selling price of the lamp is = $97.50
This price included the 7.5% sales tax.
Let the original price be x
This means [tex]x+(0.075\times x)=97.50[/tex]
[tex]x+0.075x=97.50[/tex]
[tex]1.075x=97.50[/tex]
x=90.69
The original price was $90.69
And to know how much was the tax amount we will subtract the original price from selling price.
[tex]97.50-90.69=6.81[/tex]
So, the amount of sales tax was $6.81
