Barry has been assigned to travel to Washington DC for his job. His options for travel are $25 per day for a train pass (t) and $85 per day for a rental car (c). Due to budget constraints his total travel must cost no more than $750. Which inequality below can be used to find the possible combinations of days for each of the travel options and stay within the $750 budget? 25t + 85c = 750

Question

Barry has been assigned to travel to Washington DC for his job. His options for travel are $25 per day for a train pass (t) and $85 per day for a rental car (c). Due to budget constraints his total travel must cost no more than $750. Which inequality below can be used to find the possible combinations of days for each of the travel options and stay within the $750 budget? 25t + 85c <= 750 25t - 85c <= 750 25t + 85c >= 750 25t - 85c >= 750

A

anonymous · Answer

t is the number of days using the train , 25t will be the total train cost
c is the number of days using the car, 85c will be total car cost
we need the to ensure the sum of train cost (25t) and car cost (85c) will not exceed the  $750 budget (i.e. be less than or equal to 750).
