Nine adults went to a play with seven children. Adult tickets are $11 each and children's tickets are $7 each. How many dollars more did the adults' tickets cost in total than the children's tickets in total?
Let's think: Adults = 9 * 11 = 99. Children = 7 * 7 = 49. Difference: 99 - 49 = $50. The adults' tickets cost $50 more than the children's tickets.. The answer is: 50.

The Period 1 gym class has 5 fewer than twice as many students as in the Period 2 gym class. There are 11 students in the Period 1 gym class. How many are in the Period 2 gym class?
Let's think: Let x be the number of students in the Period 8 gym class. 2x - 5 = 11. 2x = 16. x = 8.. The answer is: 8.

At a party, there are 400 students, a combination of poets, singers and tree huggers. There are 50 more poets than treehuggers at the party. If the number of tree huggers is 120, how many singers are at the party?
Let's think: Since there are 50 more poets than treehuggers at the party, the number of poets is 120 + 50 = 170. The number of poets and tree huggers at the party is 170 + 120 = 290. Since the number of attendees at the party also included singers, there are 400 - 290 = 110 singers.. The answer is: 110.

GiGi took out a big bowl of mushrooms from the refrigerator. She cut each mushroom into 4 pieces. Her twins, Kenny and Karla sprinkled mushrooms on their pizzas and baked them in the oven. Kenny grabbed a handful and sprinkled 38 mushroom pieces on his pizza. Karla scooped them up with both hands and sprinkled 42 mushroom pieces on her pizza. On the cutting board, were 8 pieces of mushrooms remaining. How many mushrooms did GiGi cut up at the beginning?
Let's think:
Kenny used 38 / 4 = 9.5 mushrooms on his pizza. Karla used 42 / 4 = 10.5 mushrooms on her pizza. Together, the twins used 9.5 + 10.5 = 20 mushrooms. There are 8 / 4 = 2 mushrooms left on the cutting board. GiGi cut up 20 + 2 = 22 mushrooms at the beginning.. The answer is: 22.
