Q. Dominique is allowed to play up to 88 hours of video games this week. They want to play video games for at least 44 hours this weekend. Which of the following can be used to represent t t , the number of hours they can play video games before the weekend?\newlineChoose 11 answer:\newline(A) 8t4 8-t \geq 4 \newline(B) 8t4 8-t \leq 4 \newline(C) t84 t-8 \geq 4 \newline(D) t84 t-8 \leq 4
  1. Understand the problem: Understand the problem.\newlineDominique is allowed to play up to 88 hours of video games for the entire week. They want to ensure they play at least 44 hours during the weekend. We need to find an equation that represents the number of hours tt they can play before the weekend.
  2. Translate the problem: Translate the problem into an inequality.\newlineSince Dominique wants to play at least 44 hours on the weekend, the time before the weekend plus the time during the weekend should not exceed 88 hours. This means the time before the weekend should be such that when you add the time they want to play during the weekend (at least 44 hours), it does not exceed 88 hours.
  3. Set up the inequality: Set up the inequality.\newlineLet tt represent the number of hours Dominique can play before the weekend. Then the total time played, including the weekend, should be less than or equal to 88 hours. If they play at least 44 hours during the weekend, the time before the weekend would be 88 hours minus the time played during the weekend. This can be represented as:\newline8t8 - t (time before the weekend) + 44 (time during the weekend) 8\leq 8 (total allowed time)
  4. Simplify the inequality: Simplify the inequality.\newlineTo find the inequality that represents the time before the weekend, we need to isolate tt. We can subtract 44 from both sides of the inequality to find the maximum time they can play before the weekend:\newline8t+488 - t + 4 \leq 8\newline8t848 - t \leq 8 - 4\newline8t48 - t \leq 4
  5. Choose the correct answer: Choose the correct answer.\newlineThe inequality we have found is 8t48 - t \leq 4. This matches answer choice (B)(B).
