A linear regression model has been developed to allow a research lab to estimate the cost of

producing a given quantity of new serum. If the incremental cost per unit in this model is equal to

$\mathrm{.}850202$ and a fixed cost of $$13\mathrm{.}69$ is required regardless of the amount of serum produced, what

is the cost to produce $5,000$ units of the serum?

$$438\mathrm{.}79$

$$4,237\mathrm{.}32$

$$68,450\mathrm{.}85$

$$4,264\mathrm{.}70$
