Inequalities in Action: Interpreting Scenarios for 8th Grade

A store sells notebooks for $3 each. If you want to buy at least 5 notebooks and have no more than $20 to spend, write an inequality to represent this situation.

• x >= 5 and 3x = 20

• x >= 5 and 3x <= 20

• x <= 5 and 3x >= 20

• x < 5 and 3x < 20

Maria has $50 to spend on books. Each book costs $8. Write an inequality to show how many books she can buy without exceeding her budget.

• b <= 6

• b = 5

• b >= 7

• b < 6

A gym charges a monthly fee of $30 plus $5 for each class attended. If you want to spend no more than $100 in a month, write an inequality to find the maximum number of classes you can attend.

• 12

• 14

• 10

Tom is saving money to buy a video game that costs $60. He currently has $15 and saves $5 each week. Write an inequality to determine how many weeks it will take for him to have enough money.

• w > 9

• w >= 9

• w < 9

• w <= 9

A concert ticket costs $45. If you want to buy tickets for yourself and at least 3 friends, but you have a budget of $200, write an inequality to represent how many tickets you can buy.

• 45x <= 200, x >= 4

• 45x < 200, x >= 3

• 45x <= 200, x < 4

• 45x <= 250, x >= 4

A farmer has 120 apples and wants to pack them into boxes. Each box can hold 8 apples. Write an inequality to determine the maximum number of boxes he can fill without exceeding the number of apples he has.

• b ≤ 10

• b ≤ 20

• b ≤ 15

• b ≤ 12

• x <= 40

• x <= 25

• x <= 30

• x <= 33

Lily wants to buy a new phone that costs $300. She has saved $120 and plans to save $20 each week. Write an inequality to find out how many weeks it will take her to save enough money for the phone.

• w = 8

• w >= 9

• w <= 10

• w < 9

A pizza place offers a deal where you can buy pizzas for $10 each. If you want to spend no more than $70, write an inequality to determine how many pizzas you can buy.

• x ≥ 5

• x ≤ 10

• 25x ≥ 1000

• 25x < 1000

• 30x ≤ 1000

• 20x ≥ 1000
