Question

Abby has 295 stamps in her collection. She wants to collect at least 485 stamps. Write and solve an inequality to determine how many more stamps Abby must collect to reach her goal. Let d represent the number of stamps Abby must collect to reach her goal.

(a) d ≥ 485 - 295
(b) d ≤ 295 - 485
(c) d ≥ 295 + 485
(d) d ≤ 295 + 485

Answer 1

Abby must collect at least 190 more stamps to reach her goal of 485 stamps.

Step-by-step explanation:

To determine how many more stamps Abby must collect to reach her goal, we can subtract the number of stamps she already has from her goal. Let d represent the number of stamps Abby must collect. So, the inequality is d ≥ 485 - 295. Simplifying, we have d ≥ 190.

This means that Abby must collect at least 190 stamps to reach her goal of 485 stamps.
