Jeanette purchased a concert ticket on a website. The original price of the ticket was $75. She used a coupon code to receive a 20% discount. The website applied a 10% service fee to the discounted price. Jeanette's ticket was less than the original price by what percent?

28%

Step-by-step explanation:

The discounted price was (1.00 - 0.20)($75), or 0.8($75) = $60.

Adding 10% to that results in (1.00 + 0.10)$60, or 0.9($60) = $54, which represents the final price including 10% service fee.

The final price is $54, down from $75.  The discount was ($75 - $54), or $21.

This discount, as a fraction of the original price, was

$21

* 100% = 28%

$75

i think it will be zero as slope has a formula of difference between initial and final distance divided by itz time interval
