Elisa purchased a concert ticket on a website. The original price of the ticket was $95. She used a coupon code to receive a 10% discount. The website applied a 10% service fee to the discounted price. Elisa's ticket was less than the original by what percent?

Respuesta :

The price of the ticket after the cupon is:

[tex]95\cdot0.9=85.5[/tex]

To this price we have to add 10%, then:

[tex]85.5\cdot1.1=94.05[/tex]

Hence the final cost of the ticket is $94.05.

To find out how less is this from the orginal price we use the rule of three:

[tex]\begin{gathered} 95\rightarrow100 \\ 94.05\rightarrow x \end{gathered}[/tex]

then this represents:

[tex]x=\frac{94.05\cdot100}{95}=99[/tex]

Therefore, Elisas's ticket was 1% less than the orginal price.
