Yes, the equation f=3n, where n is the number of cakes, models the situation.
<span>12x-4y=-8
y=3x+2 can sub for y in the first equation: 12x - 4(3x+2) = -8
Then 12x - 12x - 8 = - 8
This is true for all x, so there are infinitely many sol'ns.

Answer:
185 units
Step-by-step explanation:
Given,
The revenue function is,

Cost function,
,
Where,
x = number of units produced.
Thus, profit = revenue - cost

Differentiating with respect to x,

Again differentiating with respect to x,

For maxima or minima,
P'(x) = 0,



For x = 185,
P''(x) = negative,
Hence, for maximising the profit 185 units must be produced.
