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%.

answer: 8d

step-by-step explanation:

45+5= 50+5=55+5=60

x² + 3x + 7 = 0       [ax² + bx + c]

a = 1

b = 3

c = 7

quadratic formula:

    (+/- is this ±)
