Could someone explain the formula for this question?

Step-by-step explanation:

The modelled equation, P = 20n - 1200 is written in the slope intercept form. The slope of the line is 20. The line cuts the vertical axis at - 1200

a) the p intercept is - 1200(cost of production)

b) at the p intercept, the number,

n = 0. It means that no watches are sold. Therefore,

If the company sells 0 watches, it will lose $1200

c) the n intercept is the point where the line cuts the x axis.

At the n intercept, P = 0

0 = 20n - 1200

20n = 1200

n = 1200/20

n = 60

d) if the company sells 60 watches, it will lose $0

the second option
