Gasoline price changed from $3.25/gallon to $1.30/gallon in one week. What is the percent of change? PLZ I need it fast!! I will give 10 points

The percent of change is -60%.

Step-by-step explanation:

To find the percentage of change, we find the percentage of the final value, considering the initial valuie is 100%, and then we subtract 100% by the percengate found.

In this question:

Initial price of $3.25 per gallon, which is 100% = 1.

Final value of $1.30, which is x. So

$3.25 - 1

$1.30 - x

The initial value of 0.4 = 40% of the initial value.

So the percent of change is a decrease of 100% - 40% = 60%, that is, -60%.

arithmetic sequence

step-by-step explanation:

given that a sequence has terms as

19, 15, 11,

this is represented on a graph

the pattern indicates that the sequence is an arithmetic sequence with i term

a=19 and common difference d =-4

any general term

thus the sequence is reduced by 4 for each successive term starting from 1 and nth term is

24-5n.

first negative term would start after 5th term

5th term =24-25< 0

from 5th term onwards the sequence would be negative.
