Question

Bella is typing a 400 word essay. She types 50 words in 2 minutes.

Answer 1

Answer:

$y=25x$

Step-by-step explanation:

If Bella types 50 words in 2 minutes, we can divide 50 by 2 to see how many words she types in 1 minute.

$50/2=25$

So, Bella types 25 words per minute. When she first began writing her essay, she did not have words to start with, so there is no y-intercept ($b$).

Therefore, the equation that represents this relation is $y=25x$.

Solving the equation

We can divide 400 by 25 to determine how many minutes it would take her to finish her essay.

$\frac{400}{25} =16$

Therefore, it will take her 16 minutes to complete her essay.
