Question

24. You need to write an essay that has at least 500 words. You have written 285 words so far.

Answer 1

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"

$w+285\geq 500$

Solve for w

Subtract 285 both sides

$w\geq 500-285$

$w\geq 215$

The minimum number of words left to write is 215
