Dylan opened a credit card account with $750.00 of available credit. now that he has made some purchases, dylan's account only has $615.00 of available credit. what is the percentage decrease of the amount of available credit in dylan's account?

The percentage decrease = 18%.

Step-by-step explanation:

The formula used to find the percent change (increase or decrease) is:

x 100

Since the original amount of available credit is $750 and the new amount available is $615, we can use our formula above to calculate the percent decrease of available credit:

= .18 x 100 = 18%.

for finding the midpoint of any given 2 pair of points simply add the respective x coordinates with other x coordinate and the y coordinate with other y coordinate and divide them by 2

in your question it will be :

(3+1)/2 for the x coordinate of mid point i.e 2

[8+(-4)]/2 for the y coordinate of midpoint i.e 2

so coordinates of mid point of points (3,8) and (1,-4) will be (2,2)

answer: a.   one is a factor of every whole number since every number is divisible by itself.
