Answer:
Step-by-step explanation:
That $15,000 sounds like an annual amount, not a monthly or weekly amount. In the absence of clarification of this, I will include that $15,000 in the following calculations:
Let the # of cookies baked be z and the number of cakes be k.
Then:
Total cost = $15,000 + ($0.25/cookie)z + ($3.53/cake)k
In this specific case, where the number of cookies is z and the number of cakes is k, the formula
Total cost = $15,000 + ($0.25/cookie)z + ($3.53/cake)k
becomes ...
Total cost (z, k) = $15,000 + ($0.25/cookie)(400) + ($3.53/cake)(200),
and this works out to:
TC (z, k) = $15,000 + $100 + $706 = $15,000 + $806 = $15,806.
No cakes or cookies could be good enough to warrant production costs that high!
