“Sarah wants to buy some candy. Each candy costs $4. Sarah has $20. Write an inequality to represent the number of candies (x) Sarah can buy. Solve the inequality 4x ≤ 20. Explain your solution in words and using an inequality symbol. A plant is already 3 inches tall, and it will grow 1 inch each week. Ben wants the plant to be at least 10 inches tall. Write an inequality to represent the number of weeks (w) Ben needs to wait. Solve the inequality w + 3 ≥ 10. Explain your solution in words and using an inequality symbol. A store is offering a discount of $2 off every item. Lisa wants to buy a toy that originally costs more than $12 after the discount. Write an inequality to represent the original price (z) of the toy. Solve the inequality -2z > 12. Explain your solution in words and using an inequality symbol.”
