Answer:

38%

Step-by-step explanation:

Change \frac{7}{25} to a percent, that is

A clothing business finds there is a linear relationship between the number of shirts, n, it can sell and the price, p, it can c
Vitek1552 [10]

Answer:

p = -0.004n+34

Step-by-step explanation:

The slope of the linear equation can be found by using the two given points (30, 1000) and (22, 3000):

m = \frac{p_1-p_0}{n_1-n_0}= \frac{30-22}{1000-3000}\\m=-0.004

Applying the point (30, 1000) to the general form of a linear equation with m =-0.004, gives us the linear relationship between price (p) and number of shirts (n):

(p-p_0) = m(n-n_0)\\p-30=-0.004(n-1000)\\p=-0.004n+34
