Mick paid $2.94 in sales tax on an item that cost $42.00 before tax.
Let the rate of tax be x then
[tex] 42*\frac{x}{100}=2.94\\
\\
\text{Simplify we get}\\
\\
42x=294\\
\\
\text{Divide both the sides by 42 we get}\\
\\
x= 7\\
\\
[/tex]
Hence the sales tax percentage is 7%.
Sales tax for an item that costs $58.00 before tax= [tex] 58*\frac{7}{100}\\ [/tex]
=[tex] \frac{58*7}{100} =\frac{406}{100}=4.06 [/tex]
Sales tax for an item that costs $58.00 before tax= $4.06
