Jason draws a line in the sand at the beach the line is 7/8 feet long he wants to divide the line into sections that are 1 8 fee

abruzzese [7]

The answer is 7 sections
In this type of question, you just need to divide the total length of the line that drawn by Jason with the length of sections that Jason want.

So, the calculation would be:

(7/8) / (1/8)

= 7/8 x 8/1

= 7 amount of sections

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):

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