Answer:
Step-by-step explanation:
Profit is expressed as Revenue - Cost. Therefore
P = R - C
P(X) = R(x) - C(X)
Let x represent the number of units produced and sold.
a) A manufacturer has a monthly fixed cost of $22,500 and a production cost of $6 for each unit produced. This means that the cost function would be
C(x) = 22500 + 6x
b) The product sells for $9/unit. This means that the revenue function would be
R(x) = 9x
c) The profit function would be
P(x) = R(x) - C(x) = 9x - (22500 + 6x)
P(x) = 9x - 22500 - 6x
P(x) = 3x - 22500
d) when x = 6000,
P = 3 × 6000 - 22500 = 18000 - 22500 = -$4500. loss is made
when x = 9000,
P = 3 × 9000 - 22500 = 27000 - 22500 = $4500. profit is made
XY in cm
x-1+2x-1+2x-1=28
5x-3=28
5x=31
x=31/5
XY = (31/5×2-1) = (6.2×2-1) = 11.4 cm
Awnser 3 is the right one
123 is the answer to this equation I think
