Shauna is buying tickets for a group of baseball games. She wants tickets for at least 5 games. Each ticket for an afternoon game costs $17.50 and each ticket for an evening game costs $32. Shauna wants to spend no more than $250.

Which system of inequalities can Shauna use to find the number of tickets she can buy?

• x + y ≥ 5

  and

  250 ≥ 17.5x + 32

• x + y ≤ 5

  and

  250 ≥ 17.5x + 32y

• x + y ≥ 250

  and

  5 ≥ 17.5x + 32y

• x + y ≤ 250

  and

  5 ≤ 17.5x + 32y
