How many puzzles will Erica have left to complete in her Sudoku puzzle book?

Question:

If Erica has completed 2/5 of the Sudoku puzzle book, which contains 60 puzzles, and she completes 8 more puzzles, how many will she have left to complete?

Answer:

Erica will have 28 puzzles left to complete in her Sudoku puzzle book.

Explanation:

To find out how many puzzles Erica will have left to complete, we need to subtract the number of puzzles she has already completed from the total number of puzzles in the book.

Erica has completed 2/5 of the 60 puzzles, which is equal to 2/5 * 60 = 24 puzzles. If she completes 8 more, she will have 24 + 8 = 32 puzzles completed. To find out how many puzzles she will have left to complete, we subtract 32 from the total number of puzzles in the book: 60 - 32 = 28 puzzles.
