A baker has 253 eggs in the refrigerator. If his cake recipe takes 4 eggs, and he makes as many cakes as possible, how many eggs will he NOT use? (HINT: the remaining egg that isn't used!)

• 63 eggs

• 1 egg

• 180 eggs

Answer explanation

The baker has 253 eggs in the refrigerator. Since his cake recipe requires 4 eggs, he can make 63 cakes (253 divided by 4). After making the cakes, he will have 1 egg left, which he will not use. Therefore, the correct answer is '1 egg'. The remaining eggs will be used in making the cakes.

Ted fills 8 cars with gasoline. His uncle fills 24 cars with gasoline. Each car holds 15 gallons of gasoline. How much gasoline do Ted and his uncle use filling all the cars?

• 480 gallons

• 39 gallons

• 9 gallons

Answer explanation

To find out how much gasoline Ted and his uncle use filling all the cars, we need to calculate the total number of cars filled by both of them. Ted fills 8 cars, and his uncle fills 24 cars, making a total of 32 cars. Each car holds 15 gallons of gasoline. So, the total amount of gasoline used is 32 cars multiplied by 15 gallons per car, which equals 480 gallons. Therefore, Ted and his uncle use 480 gallons of gasoline filling all the cars.

The county library just moved to a new location. The librarian needs to place all 3,660 fiction books on 6 bookcases. If the librarian places the same number of books on each bookcase, how many bookcases will be needed to hold all the books?

• 21,960 books

• 610 books

• 3,654 books

Answer explanation

To determine the number of bookcases needed, divide the total number of fiction books (3,660) by the number of books placed on each bookcase. This will give us the number of bookcases required. In this case, dividing 3,660 by 6 gives us 610 books per bookcase. Therefore, 610 bookcases will be needed to hold all the books.
