Question

The number of words carla can type varies directly with the number of minutes she types. carla can type 114 words in 3 minutes. which equation represents the number of words, y, that carla can type in x minutes?

Answer 1

114 words /3 minutes = 38 words/minute

The amount of words she can type per minute is directly related to the number of minutes she types. So it is a linear equation.


y = 38 * x


In three minutes (x = 3), y = 114 words.
