Answer:
45x + 1750 > 4000
Step-by-step explanation:
We know that Chris has already typed 1750 words, so that can be considered the "initial condition". His speed is 45 words per minute, so if we multiply 45 by x, we will get the total number of words he typed in x minutes.
Adding that total number of words typed in x minutes to the initial 1750, we want to make sure this sum is greater than 4000 because the problem says that the paper "has to be more than 4000 words". So, we use the ">" symbol:
45 * x + 1750 > 4000
45x + 1750 > 4000
The answer is thus 45x + 1750 > 4000.
Answer:
1750 + 45n > 4000
4n > 2250
n > 50
Step-by-step explanation:
Chris types at an average speed of 45 words per minute.
So in n minutes, he types 45n words
He has already typed 1,750 words of his final paper.
So after n more minutes, he types a total of
1750 + 45n words
The paper has to be more than 4,000 words.
1750 + 45n > 4000
4n > 2250
n > 50
