If sales tax on a 16.00 dvd is $1.32 find the sales tax on a $120.00 dvd player

 tax = $1.32 / $16.00 = 0.0825 = 8.25 % 

tax ofr $120.00 DVD = 0.0825 x $120.00 = $9.90

We know that,

A $16.00 DVD player has a sales tax of $1.32, 

And $120.00 divided by $16.00 = $7.50.

Since $1.32 is the sales tax on a $16.00 DVD,

We multiply $1.32 by $7.50, which is $9.90.

So, the sales tax on a $120.00 DVD player is $9.90
