The right answer is Option B.
Step-by-step explanation:
No. of baseball cards = 35
Increase = 20%
Number of increased cards = 20% of 35
[tex]Increased\ cards = \frac{20}{100}*35\\Increased\ cards=\frac{700}{100}\\Increased\ cards=7[/tex]
Total cards = 35+7 = 42
No. of cards sold = 8
Cards left = Total cards - No. of cards sold
[tex]Cards\ left=42-8\\Cards\ left=34[/tex]
The right answer is Option B.
