  1. Calculate Unit Price: Find the unit price per sandwich by dividing the cost by the number of sandwiches for any given amount.\newlineCalculation: 21÷3=721 \div 3 = 7 dollars per sandwich.
  2. Calculate Cost of 1212 Sandwiches: Use the unit price to calculate the cost of 1212 sandwiches.\newlineCalculation: 77 dollars/sandwich ×12\times 12 sandwiches = 8484 dollars.
