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.

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

Step-by-step 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

i will pick c put check it over to be sure

step-by-step explanation:

hello from mrbilldoesmath!

answer:

25x^2 + 90x + 84

discussion:

mn(x) = m(n(x)) = m( 5x + 9) =

(5x + 9)^2 + 3 =>

25x^2 + 90x + 9^2 + 3 =

25x^2 + 90x + 84                 (as 9^2 = 9*9 = 81)

which is the second choice
