An electronics store discovers that it can sell 5 televisions per day by pricing them at $150. When the televisions are on sale
Nataly [62]

Answer:

p = -10x + 200

m = -10x^2 +200x

Step-by-step explanation:

We know that at a price of $ 150, 5 televisions are sold and at a price of $ 100, 10 televisions are sold.

We must write a linear equation for this situation.

The equation of the line will have the following form

p = mx + b

Where m is the slope of the line and b is the intercept with the p axis

m=\frac{y_2-y_1}{x_2-x_1}\\\\m=\frac{100-150}{10-5}=-10

b=p_1-mx_1\\\\b=150-(-10)(5)\\\\b=200

The equation is:

p = -10x + 200

Now we know that the revenue m is the product of the price p for the quantity sold x.

m = p * x

m=(-10x + 200)*x

m = -10x^2 +200x
