Question

Dylan opened a credit card account with $750.00 of available credit. Now that he has made some purchases, Dylan's account only has $412.50 of available credit. What is the percentage decrease of the amount of available credit in Dylan's account?

A. 34%
B. 55%
C. 45%
D. 82%

Answer 1

C. 45%

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 =
`(decrease\ in\ credit)/(initial\ credit)`×100

=
`(337.50)/(750.00)`×100

=
`(9)/(20)`×100

= 9×5

= 45%

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