A coffee shop orders at most $3,500 worth of coffee and tea. The shop needs to make a profit of at least $1,900 on the order. The possible combinations of coffee and tea for this order are given by this system of inequalities, where c = pounds of coffee and t = pounds of tea:
6c + 13t ≤ 3,500
3.50c + 4t ≥ 1,900
Which graph's shaded region represents the possible combinations of coffee and tea for this order?
