Question

I need help on this question my teacher said the answer is 153 words and I checked online and it gives me the answer as 83.

Answer 1

B. 83 words per minute

Step-by-step explanation:

Given the below equation of the line;

`y=-1.4x+117.8`

where y = typing speed

x = age in years

Given x = 25 years, let's go ahead and determine the value of y by substituting x with 25 and solving for y;

`\begin{gathered} y=-1.4(25)+117.8 \\ y=-35+117.8 \\ y=82.8\approx83 \end{gathered}`

So if one is 25 years of age, the typing speed will be 83 words per minute
