Carol’s class had 25 students on roll. After some new students join her class, the number of students increases to 36. Write an equation to determine the number of students who joined Carol's class.

• 25 + x = 36

• x – 36 = 25

• 36x = 25

• 36 + x = –25

Which choice models this situation? Marcus needs to sell 25 tickets to a fundraiser by Friday. So far, he has sold 9 tickets. How many tickets does he still need to sell?

• t - 9 = 25

• t + 9 = 25

• 9t = 25

• t/9 = 25

Which choice models this situation? Lisa finished a race in 58 seconds. This was 4 seconds faster than her best practice time. What was Lindsey's best practice time?

• t + 4 = 58

• t - 4 = 58

• 4t = 58

• t/4 = 58

Write the equation for the model. (white square=1 rectangle=x red square = -1)

• 7=x+3

• 7=x+(-3)

• 7=-x+3

• -7=x-3

Solve for x

• x = 4

• x = 1

• 2x = 4

• x = 2

Which choice models this situation?
Taylor has read 125 pages in a book. The book has a total of 262 pages. How many pages does she have left to read to finish the book?

• p - 125 = 262

• p + 125 = 262

• 125p = 262

• p/125 = 262

Which choice models this situation?
Last week, Tina worked 35 hours in 5 days. She worked the same number of hours each day. How many hours did she work each day?

• h - 5 = 35

• h + 5 = 35

• 5h = 35

• h/5 = 35

Which choice models this situation? Jack needed new pencils for school today. He took 6 pencils from a new box of pencils. If there are 18 pencils left in the box, how many pencils were in the brand new box?

• p - 6 = 18

• p + 6 = 18

• 6p = 18

• p/6 = 18

Which choice models this situation? Anna participated in a read-a-thon. Mr. Cole pledged $4 per book and gave Anna $44. How many books did Anna read?

• b - 4 = 44

• b + 4 = 33

• 4b = 44

• b/4 = 44
