Pankaj is planning lunch for his wedding anniversary. At one restaurant, the cost per person for lunch is \( \$ 15 \) with an additional one-time set-up charge of \( \$ 35 . \) Pankaj has a maximum budget of \( \$ 150 . \) If \( p \) represents the number of people (including Pankaj) who will attend the lunch, which of the following inequalities represents the number of people who can attend within budget?

  • A. \( 15 p \leq 150+35 \)
  • B. \( 35 \leq 150-15 p \)
  • C. \( 15 p \geq 150-35 \)
  • D. \( 35 \geq 150-15 p \)

Step-by-step solution

The total cost is \(15p + 35\), which must be ≤ 150. Rearranging gives \(35 \leq 150 - 15p\), which matches option B.
