Use the formula y=50x-25
Approximately how many minutes will it take a student to type a 2500 word essay if in 8 minutes they can type 375 words and in 15 minutes they can type 725 words
so in your equation, y is the number of words and x is the number of minutes
so set y = 2500
50x - 25 = 2500
50x = 2525
x = 50.5
so it will take 50.5 minutes or 50 minutes and 30 seconds.
y= 50x – 25

To find out approximately how many minutes it will take a student to type a 2500 word essay, we can use the formula y = 50x - 25, where y represents the number of words typed, and x represents the number of minutes taken.
We are given two data points:
1) In 8 minutes, the student can type 375 words.
2) In 15 minutes, the student can type 725 words.
Let's use these data points to create a system of equations and solve for x.
Using the first data point, we have:
375 = 50(8) - 25
375 = 400 - 25
375 = 375
Using the second data point, we have:
725 = 50(15) - 25
725 = 750 - 25
725 = 725
Since both equations are equal, we can conclude that the given points lie on the line y = 50x - 25.
Now, let's find the value of x when y = 2500:
2500 = 50x - 25
2525 = 50x
x = 2525 / 50
x = 50.5
Therefore, it will take approximately 50.5 minutes for the student to type a 2500 word essay.
