Answer:
8
Step-by-step explanation:
Before Fred bought 9 more, he had 4. Since 4 is half the number he started with, he started with 8 comic books.
2)Since the score is 750, then the annual rate is 9.25% (see the table)
Then monthly rate:9.25/12=0.77%.
Then compute 0.77% from <span> $2,375.00 like this:
</span>

Answer: interest to pay: $18.30.
3)Compute monthly rate for first account:
9.75/12=0.81%
Compute 0.81% of $<span>1,675.00 like this:</span>

Second account:
compute monthly rate: 12.5/12=1.04%.
Then compute

Conclusion:
Monthly interest is $13.5+$17.4=$30.9
-2x+3y+3. Just add the similar terms
