Describe the following relationship using a mathematical expression: Galina must read 1,000 pages by the end of the month. She has already completed one book that was 342 pages and another book that was 398 pages. She is currently on page 54 of a third book. How many pages more does she have to read to meet the 1,000-page goal?(1 point) Responses 1,000−(342 398 54) 1,000 minus left parenthesis 342 plus 398 plus 54 right parenthesis 1,000÷3 1,000 divided by 3 1,000−342−398 1,000 minus 342 minus 398 342 398 54

The relationship can be represented using the mathematical expression: 1,000 − (342 + 398 + 54)

This expression calculates the difference between 1,000 and the sum of pages read from the three books.
