Question

Fatim is hosting a viewing party for the new movie black Panther. Fatim decided to change ticket prices from $17.99 to $12.25 a ticket . what is the percent change as an increase or decrease? ​

Answer 1

Answer:

-31.9%

Step-by-step explanation:

In this problem, the initial price of the ticket for the movie Black Panther is

$p_i = \ 17.99$

Later, the price of the ticket is decreased to

$p_f = \ 12.25$

The percent change can be written as

$c=\frac{p_f-p_i}{p_i}\cdot 100$

Which is the ratio between the difference in price and the original price, multiplied by 100.

By substituting the values inside the formula, we find:

$c=\frac{12.25-17.99}{17.99}\cdot 100=-31.9\%$

Where the negative sign indicates a decrease.
