Step-by-Step Solution
Step 1: Determine the number of letters in the alphabet
The English alphabet consists of 26 letters, from 'a' to 'z'. This is the fundamental quantity we will be working with to calculate the total letters written.
Step 2: Calculate letters written in the first two full repetitions
Elise writes the full alphabet twice. To find the total letters written in this step, we multiply the number of letters in the alphabet (26) by 2.
Step 3: Calculate letters written in half a repetition
Next, Elise writes half of the alphabet once. We calculate this by multiplying the total number of letters (26) by 21.
Step 4: Calculate the total letters written before the final repetition
Before the final step, Elise has written the alphabet twice in full and once halfway. We add the letters from the first two full repetitions (52) and the half repetition (13) to get the initial total.
Step 5: Calculate letters written in the final repetition
Finally, Elise re-writes everything she has already written. This means she writes the current total number of letters again, which is 65.
Step 6: Calculate the grand total of letters written
To find the grand total, we add the letters written initially (65) to the letters written in the final repetition (65). This gives us the complete count of all letters Elise has written.
