Answer:
sales-tax rate = 6%
Step-by-step explanation:
The price of a silk scarf is $32. The sales tax is $1.92
Let the sale tax rate be s%
Price of silk scarf = $32
Sale tax = s% of 32
Sale tax = $1.92
Thus,
s% of 32 = 1.92
First we change s% to decimal
\(\dfrac{s}{100}\times 32=1.92\)
\(s=\dfrac{1.92\times 100}{32}\)
\(s=6\%\)
Hence, The sales-tax rate is 6%
