You plan to sell cookies for your Math Club. It costs $0.15 each to bake a cookie and $25.00 for packaging materials. The first 48 cookies are samples and will not be sold.

A. Write a function for the average cost of a cookie

B. What is the average cost if 1000 cookies are baked?​

Answer:

see below!

Step-by-step explanation:

A) [tex]\frac{.15x + 25 + 48(.15)}{x + 48}[/tex] which can be simplified to [tex]\frac{32.2 + .15x}{x + 48}[/tex] = f(x)

  • x in this equation is the cookies because the number of cookies someone wants to make is unknown
  • 25 is the total cost of materials used total
  • 48(.15) would be the cost of the samples
  • f(x) is the answer for when you plug in x

B)

plug in 952 to x because x is the number of cookies left that you need to bake since 48 has been taken out already for the samples

[tex]\frac{32.2 + .15(952)}{952 + 48}[/tex] -----> [tex]\frac{32.2 + 142.8}{1000}[/tex]------> [tex]\frac{175}{1000}[/tex] ------> $0.175 or 17.5 cents

hope this helps.......
