Question

amir makes and sells silver jewelry. he finds that if he charges 40 dollars for a pendant ,he can sell 200 pendants each month, but when he charges 45 dollars, he can only sell 175 per month. Find a linear model for the demand for pendants D as a function of the price x.

Answer 1

To find a linear model for the demand for pendants, use the slope-intercept form of a linear equation.

Step-by-step explanation:

To find a linear model for the demand for pendants, we can use the given information to create an equation in the form D = mx + b, where D represents the demand, x represents the price, m represents the slope, and b represents the y-intercept.

Using the two data points given, we can calculate the slope:

Slope (m) = (175 - 200) / (45 - 40)

Next, we can choose one of the data points to solve for the y-intercept:

200 = (40 * slope) + y-intercept

Finally, we can substitute the values of the slope and y-intercept into the equation to get the linear model for the demand for pendants.
