Question

Devin is collecting signatures for a petition to open a new park in her town. She needs to collect at least 1,000 signatures before she can schedule a meeting with the mayor. She already has 380 signatures. If each petition page holds 80 signatures, which inequality best shows how many more pages (p) Devin needs?

7 ≤ p
8 ≤ p
8 < p
9 < p

Answer 1

She needs at least 1000 − 380 = 620 more signatures. At 80 signatures per page, p must satisfy 80p ≥ 620, so p ≥ 7.75. Since p is whole pages, p ≥ 8.

Answer: 8 ≤ p.
