He buys 3 bags of potato chips for $1.00 each so that’s 3*1 = $<<3*1=3.00>>3.00
The chips are $3.00, the creme fraiche is $5.00 and the caviar is $73.00 for a total of 3+5+73 = $<<3+5+73=81.00>>81.00
The appetizer costs $81.00 and will serve 3 people so it will cost 81/3 = $<<81/3=27.00>>27.00 per person
