Grade 7 | Unit 6 | Lesson 2: Reasoning about Contexts with Tape Diagrams | Practice Problems

The table shows the number of apples and the total weight of the apples.

number of apples	weight of apples (grams)
2	511
5	1200
8	2016

Estimate the weight of 6 apples.

• About 1200 grams

• About 1500 grams

• About 1700 grams

• About 2000 grams

Select all stories that the tape diagram can represent.

• There are 87 children and 39 adults at a show. The seating in the theater is split into 4 equal sections.

• There are 87 first graders in after-care. After 39 students are picked up, the teacher put the remaining students into 4 groups for an activity.

• Lin buys a pack of 87 pencils. She gives 39 to her teacher and shared the remaining pencils between herself and 3 friends.

• Andre buys 4 packs of paper clips with 39 paper clips in each. Then he gives 87 paper clips to his teacher.

• Diego’s family spends $87 on 4 tickets to the fair and a $39 dinner.

Andre wants to save $40 to buy a gift for his dad. Andre’s neighbor will pay him weekly to mow the lawn, but Andre always gives a $2 donation to the food bank in weeks when he earns money. Andre calculates that it will take him 5 weeks to earn the money for his dad’s gift. He draws a tape diagram to represent the situation. Explain how the parts of the tape diagram represent the story.

How much does Andre’s neighbor pay him each week to mow the lawn?

• $8

• $10

• $12

• $15

• $20

Solve each equation.
