Question

The sales tax on a ceiling fan was $6.80. If the sale tax rate was 6 percent, what was the marked price of the fan?

Answer 1

The sales tax on a ceiling fan is $6.80 that is 6%. Let $x be the price of the fan, then $x is 100% and you can use proportion:

the ratio $6.80 to 6% is the same as

the ratio $x to 100%.

Mathematically you can write:

`(6.80)/(6) =(x)/(100)`.

Express x:

`x=(6.80\cdot 100)/(6) =113.(3)=113.3333....`

Answer: the marked price of the fan was $113.33
