Answer: 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

The answer is A because we dont know how many baseball cards blake had so you would add. 25 to b
