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?
You want the combination of costs (train pass and rental car) to be less than or equal to the budget constraint. Therefore: 25*t + 85*c <= 750
