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?

Devin needs at least 1,000 signatures and already has 380, so the pages must provide at least 1,000 − 380 = 620 more signatures. Since each page holds 80 signatures, 80p ≥ 620, which gives p ≥ 7.75. She needs a whole number of pages, so she needs at least 8 pages: “8 is less than or equal to p.”
