A store sells shirts to the public at one pricing scale and wholesale at another pricing scale. The tables below describe the cost, y, of x shirts.

Public
A 2-column table with 3 rows. Column 1 is labeled x with entries 2, 5, 9. Column 2 is labeled y with entries 24, 60, 108.
Wholesale
A 2-column table with 3 rows. Column 1 is labeled x with entries 18, 35, 50. Column 2 is labeled y with entries 162, 315, 360.

How do the slopes of the lines created by each table compare?
The slope of the Public table is Three-fourths of the slope of the Wholesale table.
The slope of the Wholesale table is Three-fourths of the slope of the Public table.
The slope of the Public table is 12 times greater than the slope of the Wholesale table.

A 2-column table with 3 rows. Column 1 is labeled x with entries 18, 35, 40. Column 2 is labeled y with entries 162, 315, 360.

Answer:

(B)The slope of the Wholesale table is Three-fourths of the slope of the Public table.

Step-by-step explanation:

Given the points from the public table

(2,24),(5,60),(9,108)

Slope[tex]=\dfrac{60-24}{5-2} =\dfrac{36}{3}=12[/tex]

Given the points from the wholesale table

(18,162),(35,315),(50,360)

Slope[tex]=\dfrac{315-162}{35-18} =\dfrac{153}{17}=9[/tex]

[tex]\frac{3}{4}X$Slope of Public Table=Slope of Wholesale Table$ \\\dfrac{3}{4} X 12=9[/tex]

Therefore, we can see that the slope of the Wholesale table is Three-fourths of the slope of the Public table.
