Answer:
128 lawn mowers were manufactured.
Step-by-step explanation:
Let's call z the number of manufactured lawn mowers
The general expenses are: $ 34 816
The costs per lawn mower are $388(z)
We know that:
Total cost (c) = Variable cost + fixed cost
So
[tex]c = \$388(z) + \$34\ 816[/tex]
The average cost of production Cp is equal to c/z
So:
[tex]Cp = \frac{388(z) + 34816}{z}\\\\Cp = 388 + \frac{34816}{z}[/tex]
We know that Cp = 660.
Finally:
[tex]660 = 388 + \frac{34816}{z}\\\\z = \frac{34816}{272}\\\\z = 128[/tex]
