Answer:

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

This question is incomplete

Complete Question

Mr Sampson fills the family pool with water for the summer.After two hours,the water has reached a depth of 2.5 feet. After three hours,the water level has risen to 3 3/4 feet.If the relationship between time and water depth is proportional,what is the constant of proportionality?

Answer:

1.33

Step-by-step explanation:

Time is proportional to Depth

Hence:

T ∝ D

T = kD

Where k is the constant of proportionality

After two hours,the water has reached a depth of 2.5 feet. After three hours,the water level has risen to 3 3/4 feet.

Total number of hours now is 3 + 2 = 5 hours

5 = k × 3 3/4

5 = k × 3.75

k = 5/3.75

k = 1.33
