Answer:
P = -0.004Q + 149
Step-by-step explanation:
The general form of the linear equation is:
The slope of the equation (a) can be found by using the two given points (4,000; $133) and (27,000; $41)
Applying the point (4,000; $133) to the equation below yields in the linear equation for Price as a function of the number of shirts:
The linear equation is:
P = -0.004Q + 149
Answer: D.
You can get the lowest price at Store C
B- Not sure if it's a line
C- y=(-x/2)-6
D- y=4x-12
E- y=(2/5)x-10
2x² - 4x - 30
2(x²) - 2(4x) - 2(15)
2(x² - 4x - 15)
5/2 or 2.5
Hope this helps!
