Answer
Opsie 1: Akkommodasie vir 4 mense teen R1 550.
Ontbyt teen R95 x 4 is R380.
Totale bedrag: R1 550 + R380 = R1 930.
Opsie 2: Akkommodasie met ontbyt R550 + R500 per persoon vir 4 mense = R2 200.
By die Moremi Wildreservaat is daar 5 selfsorgeneed wat 4 mense kan huisves en 3 selfsorgeneed wat 6 mense kan huisves, teen ekstra koste, indien daar slegs 4 mense is.
