Question

Someone please help me with this question.

Answer 1

Answer:

More milk production:  Holstein Farm

About how much more:  52 gallons (approx.)

Step-by-step explanation:

Looking at the table:

We find the slope (gallons/number of cows) by dividing gallons with number of cows from each row to get this:

175/30 ≈ 348/60 ≈ 526/90 etc.

= 5.8

Looking at the graph:

We find the slope by taking 2 points from the graph and the slope would be:

Change in y coordinates/ Change in x-coordinates

Taking the 2 points:

(50,300)  &  (150,1000)

slope = (1000-300)/(150-50) = 700/100 = 7

Lets find milk production of 2 farms:

Holstein:  drawing a line connecting the points and looking at x = 60, we see the gallons would be around 400.

Jersey: 60 days is 348 gallons (in table)

So, Holstein Farm would produce more milk in 2-month period.

How much more???

400 - 348 gallons ≈ 52 gallons (approx.)
