If Tony the Tiger has 65 stripes in total and 20 on his head, how many are on his back?

• 20

• 45

• 65

• 85

Which equation represents the number of stripes on Tony's back?

• 20 + X = 65

• X - 20 = 65

• 65 - X = 20

• X + 65 = 20

Tiffany the Tiger had 55 pieces of cereal fall out. If she has 32 left, how many did she start with?

• 110

• 87

• 55

• 32

What equation can be used to find the total number of cereal pieces Tiffany started with?

• X - 55 = 32

• X + 55 = 32

• X + 32 = 55

• 32 - X = 55
