Answer

Explanation:

Step1: Calculate variable cost per cake

The variable cost per cake is the sum of the cost of making the cake, the box, and the bag. So $5 + 1.25+0.18=6.43$ dollars per cake. Let $n$ be the number of cakes. The variable - cost part of the cost function is $6.43n$.

Step2: Calculate fixed costs

The fixed costs are the rent, electricity, and advertising costs. So $900 + 80+95 = 1075$ dollars per month.

Step3: Form the cost function

The cost function $C$ is the sum of the variable cost and the fixed cost. So $C = 6.43n+1075$.

Answer:

B. $C = 6.43n+1075$
