The sales tax is around 7%. And the price of the stereo is 35 dollars.
Now, let’s solve for the total price of the stereo plus the sales tax
=> 7% convert this to decimals.
=> 7% / 100% = 0.07% (notice that 7 is in the hundredths place)
Now, let’s multiply this by 35 to get the 7% value of 35 dollars
=> 35 * 0.07 = 2.45 dollars
Next is to add this 2.45 dollars by 35 to get the total price of the stereo
=> 35 dollars + 2.45 dollars = 37.45 dollars
