Blake has b baseball cards. his aunt gave him more cards, increasing his total number of cards by 25%. which expression represents blake’s total number of cards now? a. b + 0.25 b. b − 0.75b c. 1.25b d. 0.75b

C. 1.25b

Step-by-step explanation:

Given : Blake has b baseball cards.

His aunt gave him more cards, increasing his total number of cards by 25%.

We can write 25% as 0.25.

Now, 25% of baseball cards will be : 0.25 x b= 0.25b

Now, the expression represents Blake’s total number of cards now :

b+0.25b= (1+0.25)b  [t by distributive property  ba+ca=(b+c)a]

=1.25b

Hence, the correct expression represents Blake’s total number of cards  :    

1.25 b
