Some kombis passed by the road going to her university, though one would have to walk a distance to reach the university. And one would need G$10, for a single trip. That means that each day, a person would require G$20 and with the school opening six days a week, usually, that would be G$120 per person every week.
In a month, that would be G$480 to G$500, only for transport without any food on top of that.
The minimum wage currently was G$1,100 and with several companies closed, people weren't having it easy.
For a university student, one would need that G$500 for transport, food and rent totaling roughly G$2,000 or even more.
Darica's act of providing free transport would lessen this burden on students. And since she aimed to help the kids save money and not be stressed about where to stay, she decided to put all the expenses that the students would have to pay monthly be G$600.
