  1. Calculate Remaining Amount: Sarah started with $55\$55. To find out how much she has left after buying the shirts, we need to subtract the total cost of the shirts from her initial amount.
  2. Calculate Cost of 33 Shirts: The cost of 33 shirts priced at mm dollars each is 33 times mm, which is 3m3m dollars.
