Dylan opened a credit card account with $600.00 of available credit. Now that he has made some purchases, Dylan's account only has $378.00 of available credit. What is the percentage decrease of the amount of available credit in Dylan's account?

37 %

Step-by-step explanation:

Dylan's initial credit balance = $600.00

Credit balance after expenses = $378.00

Amount spent on purchases : $600 - $378

= $222.00.

To calculate for percentage decrease:

(Decrease / Total initial balance) * 100

%age Decrease = (222/600) * 100

= 222/6

= 111 / 3

= 37 %

It therefore means that, Dylan spent 37% of his total $600.00 to have a remaining credit balance of $378.00
