From the question we are told that:
Price of 20TVs per week
Marginal price-demand function 
Generally the The Marginal price function is mathematically given by
Therefore the equation when the demand is 20 TVs per week at $150 per TV

Giving

Therefore the Price when the demand is 100 TVs per week


Answer:
The equation of the line in slope-intercept form is:
Step-by-step explanation:
Given the points
Finding the slope




We know the slope-intercept form of the line equation is

where m is the slope and b is the y-intercept
substituting m = -10/7 and (-8, 5) in the slope-intercept form to determine the y-intercept



now substituting m = -10/7 and b = -45/7 in the slope-intercept form



Thus, the equation of the line in slope-intercept form is:

Answer:
y= (-3x +14.50) / 8
Step-by-step explanation:
Isolate the 8y
Subtract 3x from both sides
8y = -3x + 14.50
Then, isolate the left to only y
y= (-3x +14.50) / 8
P = # of hrs at pizza delivery job, c = # of hrs at car wash job
p + c < = 20 (thats less then or equal)
10.50p + 7.50c > = 130 (thats greater then or equal)
