Question

If t represents the amount of time Neda has spent typing the second letter, which equation states the rule used to determine the number of words, W, Neda has typed today?

Answer 1

W = t + 200

Explanation:

Number of words typed in the first letter = 200

The relationship between the total words typed, W and the number of seconds, t spent on the second letter :

W = number of words typed in first letter + t

W = 200 + t

Choosing any pair of values from the table :

W = 245 ; t = 45

W = 200 + 45

W = 245

Therefore, the number of words, W typed today can be represented as

W = 200 + t
