Answer:
C. 45%
Step-by-step explanation:
Initial credit in his account = $750.00
Credit in his account after some purchases = $412.50
⇒Decrease in credit = $750.00 - $412.50
⇒Decrease in credit = $337.5
percentage decrease of amount of available credit = [tex]\frac{decrease\ in\ credit}{initial\ credit}[/tex]×100
= [tex]\frac{337.50}{750.00}[/tex]×100
= [tex]\frac{9}{20}[/tex]×100
= 9×5
= 45%
∴Percentage decrease of the amount of available credit in Dylan's account is 45%
