Answer 1

Hint: A sales tax is a tax paid to a governing body for the sales of certain goods and services. The formula to calculate sales tax.
Cost of the item$ \times $sales tax$\% = $sales tax.

Complete step-by-step answer:
A sales tax is a tax paid to a governing body for the sales of certain goods and services. Usually laws allow the seller to collect funds for the tax from the consumer at the point of purchase. When a tax on goods or services is paid to a governing body directly by a consumer, it is usually called a use tax.
In mathematics, a percentage is a number or ratio that represents a fraction of 100. It is often denoted by the symbol "%" or simply as "percent" or "pct." For example, 35% is equivalent to the decimal 0.35, or the fraction.
The cost price of musical instrument$ = Rs\,12000$.
Sales tax$ = 8\% $
So total sales tax$ = 12000 \times \dfrac{8}{{100}} = 960$
Now the total amount paid by him
$ = Rs\,12000 + Rs\,960$
$ = Rs\,\,12960$

Note: We can use another method to calculate sales tax by converting percentage to decimals.
Here$8\% $means$0.08$
So sales tax$ = 12000 \times 0.08 = Rs\,\,960$
Total amount paid$ = Rs\,\,12000 + Rs\,\,960 = \,Rs\,\,12960$
