Answer: 16,250 units.
Step-by-step explanation:
This is a linear function which means that it takes the form of y = mx + c.
Y is the demand
X is the price
Find m.
= (Y₂ - Y₁) / (X₂ - X₁)
= (15,000 - 20,000) / (60 - 40)
= -250
Find c using substitution;
20,000 = -250 * 40 + c
20,000 = -10,000 + c
c = 20,000 + 10,000
c = 30,000
Linear function is;
y = -250x + 30,000
If selling price is $55;
y = -250 * 55 + 30,000
y = 16,250 units.
Without graphing, it is evident that the line given by the equation f(x) = 5x – 2 does not pass through point (a) but passes through point (b)
To do this, we need to check if the value of x yields that of y in each pair of coordinates when inserted in the function, f(x) = 5x – 2.
For point (a):
defined by coordinates (1,5)
Therefore, by substituting the value of x into:
f(x) = 3.
For point (b):
defined by. coordinates (-2, -12)
Therefore, by substituting the value of x into:
f(x) = 5x – 2,
f(x) = 5(-2) - 2
f(x) = -12

Step-by-step explanation:
We have 8y + 5 <= 37.
Therefore 8y <= 32 (subtract 5 both sides)
y <= 4 (divide 8 both sides)
