Clinton loves to cook. He makes a total of 23 different items. Clinton makes 6 different desserts, 12 appetizers, and x main courses. Which equation represents the total amount of food that Clinton cooked.

• 6 - 12 + x = 23

Simon has read 694 pages over the summer by reading 3 different books. He read 129 pages in the first book and he read 284 pages in the second book. Which equation shows how to figure out how many pages he read in the third book.

• 694 = 129 +284 - y

• 694 = 413 - y

• 694 = 129 - 284 +y

• 694 = 129 +284 +y

Jimmy had $45.00. He spent all of the money on a hat and a pair of jeans. He spent $19.00 on the pair of jeans and x dollars on the hat. Which of the following equations is true?

• $45.00 + x = $19.00

• $45.00 - x = $19.00

• x - $19.00 = $45.00

• $19.00 + $45.00 = x

Janie had 54 stamps. She gave away t stamps. She then got back twice as many as she had given away. Which expression shows how many stamps Janie has now?

• 2,500 - x

• 2,500 - 2x

There are 24 boys and 29 girls (not including Claire) attending Claire's birthday party. Which equation shows how many cupcakes

• 24 - 29 = c

• 24 + 29 = c

• 24 + 30 = c

• 24 + c = 29

Heidi collects dolls. She had 172 dolls in her collection. Heidi acquired x more dolls from a friend. She then bought twice as many dolls as she acquired from her friend from a yard sale. She now has 184 dolls in her collection. Which equation is true?

• 172 + 3x = 184

• 172 - x + 2x = 184

• 172 (3x) = 184

• 172 - 3x = 184

Crystal grew 16 tomato plants. Each plant grew 10 tomatoes. She sold x of the tomatoes she had grown. Crystal has 54 tomatoes left for herself. Which equation is true?
