The profit function, P(x), is given by subtracting the cost function from the revenue function.
The derivate of the profit function gives us the rate at which profit changes:
For x = 484, the rate of change is:
Profit is increasing by $68.44 for each additional belt
Fetures are x and y
x+y=12
23.99x+120.84y=675.28
x+y=12
multiply by -23.99 and add to other equation
-23.99x-23.99y=-287.88
<u>23.99x+120.84y=675.28 +</u>
0x+96.85y=387.4
96.85y=387.4
divde both sides by 96.85
y=4
sub back
x+y=12
x+4=12
minus 4
x=8
8 of the features costing $23.99
