Question

C 1. Write an equation that represents the profit, P, for selling n cakes. Describe how you can use this equation to find the profit. 2. Fabian uses the equation P = 4.95n − 825 to predict the profit. Does this equation make sense? Explain.

Answer 1

1) P= n(cost price - selling price) 2) explained below 3) Yes it does

Explanation:

1) and 2 ) profit= selling price - cost price

multiply by n to get total profit for n cakes

total profit= n × (selling price - cost price)

3) the equation makes sense if we assume that total cost of producing n cakes is 825 and selling price per cake is 4.95.

P= selling price - cost price

sellingp rice fro n cakes= 4.95n

P= 4.95n-825
