Mrs. King bought a dozen muffins for the students in her classroom. If she bought, 1/2 of a dozen chocolate chip, 1/4 of a dozen apple cinnamon, and 1/4 dozen banana nut, how many of each muffin did she buy?
Hint: Remember that 1 dozen muffins = 12 muffins
First, calculate what fraction of the 1 dozen muffins is of what variety.
1/2 dozen chocolate chip = 6 chocolate chip muffins
1/4 dozen apple cinnamon = 3 apple cinnamon muffins
1/4 dozen banana nut = 3 banana nut muffins
Then, add the different types of muffins and see if they add up to a dozen muffins.
6 chocolate chip + 3 apple cinnamon + 3 banana nut = 12 muffins
Kenny and Kendra each received $10 to spend at the movies. Kenny bought his ticket for $4.50 and then bought a small soda for $2.00 and popcorn for $2.50. How much money did Kenny spend, and did he have any money left? Kendra spent $4.50 for her ticket and then paid $1.75 for red licorice sticks and $2.00 for a small soda. How much money did Kendra spend, and did she have any money left?
First, add up all the money that Kenny spent at the movie theater.
Next, subtract the total amount that Kenny spent from the $10 that he was given.
So Kenny spent $9.00 at the theater and had $1.00 left.
Now, add up all the money that Kendra spent at the movie theater.
Next, subtract the total amount that Kendra spent from the $10 that she was given.
So Kendra spent $8.25 at the theater and had $1.75 left.
