Q. Dominique is allowed to play up to 8 hours of video games this week. They want to play video games for at least 4 hours this weekend. Which of the following can be used to represent t, the number of hours they can play video games before the weekend?Choose 1 answer:(A) 8−t≥4(B) 8−t≤4(C) t−8≥4(D) t−8≤4
Understand the problem: Understand the problem.Dominique is allowed to play up to 8 hours of video games for the entire week. They want to ensure they play at least 4 hours during the weekend. We need to find an equation that represents the number of hours t they can play before the weekend.
Translate the problem: Translate the problem into an inequality.Since Dominique wants to play at least 4 hours on the weekend, the time before the weekend plus the time during the weekend should not exceed 8 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 4 hours), it does not exceed 8 hours.
Set up the inequality: Set up the inequality.Let t 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 8 hours. If they play at least 4 hours during the weekend, the time before the weekend would be 8 hours minus the time played during the weekend. This can be represented as:8−t (time before the weekend) + 4 (time during the weekend) ≤8 (total allowed time)
Simplify the inequality: Simplify the inequality.To find the inequality that represents the time before the weekend, we need to isolate t. We can subtract 4 from both sides of the inequality to find the maximum time they can play before the weekend:8−t+4≤88−t≤8−48−t≤4
Choose the correct answer: Choose the correct answer.The inequality we have found is 8−t≤4. This matches answer choice (B).
