Answer:
I'm not really sure about the marked price but you could choose between these
Step-by-step explanation:
6780×13=881.4
6780-881.4=R5898.6 (the price with out the VAT)
6780×20%=1356
6780-1356=R5424 (the price with out the discount)
6780-1356-881.4=R4542.6 (the price without the discount and VAT)
