a. 34%
b. 55%
c. 45%
d. 82%

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 = ×100

                                    = ×100

                                    = ×100

                                    = 9×5

                                    = 45%

∴Percentage decrease of the amount of available credit in Dylan's account is 45%
