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.\newlineWhich 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. Total allowed hours: Dominique is allowed to play up to 88 hours of video games for the entire week. They want to ensure that they play at least 44 hours during the weekend. To find the number of hours Dominique can play before the weekend, we need to subtract the hours they plan to play during the weekend from the total allowed hours for the week.
  2. Inequality representation: Let tt represent the number of hours Dominique can play video games before the weekend. Since they want to play at least 44 hours during the weekend, the total hours played before the weekend plus the hours played during the weekend should not exceed 88 hours. This can be represented by the inequality:\newlinet+(hours played during the weekend)8t + \text{(hours played during the weekend)} \leq 8\newlineSince they want to play at least 44 hours during the weekend, we can substitute this value into the inequality:\newlinet+48t + 4 \leq 8
  3. Isolating tt in the inequality: To find the expression for tt, we need to isolate tt on one side of the inequality. We do this by subtracting 44 from both sides of the inequality:\newlinet+4484t + 4 - 4 \leq 8 - 4\newlineThis simplifies to:\newlinet4t \leq 4
  4. Number of hours before the weekend: The inequality t4t \leq 4 means that the number of hours Dominique can play video games before the weekend is 44 hours or less. This matches option (B) from the given choices.
