Answer:
we have,
total selling cost= daily price * quantity
so
for Monday;
total selling cost=200*80=16,000
for Tuesday
total selling cost=180*110=19,800
for Wednesday
total selling cost=180*120=21,600
for Thursday
total selling cost=180*130=23,400
for Friday
total selling cost=220*100=22,000
for Saturday and Sunday
total selling cost=0
now
