Question

Use the scatter plot and given information to answer the question.
The data in the plot are represented by the line of fit f(x)=3x+20.
If 50 items are sold, what is the predicted profit?

I can't figure this out.

Answer 1

Answer:

The predicted profit is $170.

Step-by-step explanation:

Tis simple. The question gives you the line of best fit equation.

Take the 50 from the question and substitute it into the equation.

f(x) = 3(50) + 20

f(x) = 150 + 20

f(x) = 170
