17 The cost to rent a bus from Company X is $950 for the first 3 hours and an additional $50 per hour for each hour after the first 3 hours. If the total cost to rent the bus from Company X for t hours, where t > 3, is $1,150, which equation represents this situation?
Correct answer: C (parsed from the explanation — this source omits an answer key for this item)
Explanation
$950 Choice C is correct. It’s given that the cost to rent a bus is for the first $50 3 hours and an additional per hour for each hour after the first 3 hours. It’s > also given that t represents the total number of hours and t 3. Therefore, the number of additional hours after the first 3 hours can be represented by the - $50 expression t 3. The cost for these additional hours is per hour, so the cost 50 -3 for the additional hours can be represented by the expression ^t h. The total cost can be calculated by adding the cost for the first 3 hours to the cost for the 950+50 -3 additional hours and can be represented by the expression ^t h. It’s also given that the total cost to rent the bus from the company for t hours is $1,150 . Thus, the equation that represents this situation is 950+50 -3 =1,150 ^t h . Choice A is incorrect and may result from conceptual errors. Choice B is incorrect and may result from conceptual errors. Choice D is incorrect and may result from conceptual errors.
