Answer:
Blake's total number of cards now: 1.25b
Step-by-step explanation:
Total number of cards now would be equal to 25% increase from b.
This means we INCREASE b by 25% OF b.
What is 25% of b???
[tex]\frac{25}{100}*b\\=0.25b[/tex]
Now we need to ADD this to original amount, b.
So, [tex]b+0.25b=1.25b[/tex]
