Answer the following question.
Out of the 300 comic books in a comic store, 30% are liked by females, males like 120, and both genders don't like the rest. What percentage of the comic books are disliked by both males and females?
Step-by-step reasoning process: The number of comic books that females like is 30 / 100 * 300 = 90 books. Together, both males and females like 90 + 120 = 210 comic books. The number of comic books that are disliked by both males and females is 300 - 210 = 90. The percentage of books that are disliked by both genders is 90 / 300 * 100 = 30%.
The answer is 30.

Answer the following question.
Dana has 15 more pencils than Jayden, who has twice as much as Marcus. How many more pencils does Dana have than Marcus, if Jayden has 20 pencils?
Step-by-step reasoning process: Dana has 15 more pencils than Jayden who has 20, so Dana has 20 + 15 = 35 pencils. Jayden has 20 pencils which is twice as much as Marcus's so Marcus has 20 / 2 = 10 pencils. Dana has 35 - 10 = 25 more pencils than Marcus.
The answer is 25.

Answer the following question.
Paul has five dogs. For every 10 pounds they weigh, they need 1 pound of dog food per day. One weighs 20 pounds. One weighs 40. Another weighs 10. One weighs 30 and the final one weighs 50 pounds. How much dog food does he need each day?
Step-by-step reasoning process: The dog's total weight is 150 because 20 + 40 + 10 + 30 + 50 = 150. They need 15 pounds a day because 150 / 10 = 15.
The answer is 15.

Answer the following question.
Jack is running a bake sale to help pay for his basketball team's uniforms. He's already sold 4 brownies for $3 each and 5 lemon squares for $2 each. If Jack's goal is to make $50 and he sells cookies for $4 each, how many cookies does he need to sell to reach his goal?
Step-by-step reasoning process: Jack earned from the brownies $3 per brownie * 4 brownies = $12. Jack earned from the lemon squares $2 per square * 5 squares = $10. He still needs to earn $50 - $12 - $10 = $28. He sells cookies for $4 each, so Jack still needs to sell $28 / $4 = 7 cookies.
The answer is 7.
