  1. Identify Value of Bills: Identify the value of each type of bill Donald has.\newlineDonald has xx twenty-dollar bills, which means each bill is worth $20\$20. He also has 11 ten-dollar bill, which is worth $10\$10.
  2. Expression for Twenty-Dollar Bills: Write an expression for the total value of the twenty-dollar bills.\newlineThe total value of the twenty-dollar bills is 2020 times the number of such bills, which is 20x20x dollars.
  3. Add Ten-Dollar Bill Value: Add the value of the ten-dollar bill to the total from Step 22.\newlineSince Donald has one ten-dollar bill, we add $10\$10 to the total value of the twenty-dollar bills to find the total amount of money Donald has. The expression becomes 20x+1020x + 10.
