Answer:
The minimum number of words left to write is 215
Step-by-step explanation:
Let
w -----> the number of words left to write
we know that
The number of words left to write plus the words written so far must be greater than or equal to 500 words
Remember that the word "at least" means "greater than or equal to"
so
[tex]w+285\geq 500[/tex]
Solve for w
Subtract 285 both sides
[tex]w\geq 500-285\\w\geq 215[/tex]
The minimum number of words left to write is 215
