Gabe bought two video games that cost $95 or less. One game cost $43. What did Gabe pay for the second video game?

• c for cost of second video game

  c + 43 ≤ 95

  c ≤ 52

  The cost for the second video game was $52 or less.

• c for cost of second video game

  c - 43 ≤ 95

  c ≤ 138

  The cost for the second video game was $138 or less.

• c for cost of second video game

  43 + c < 95

  c < 52

  The cost for the second video game was less than $52.
