I have to write a function for this problem and I'm completely lost.

Question

Alan's camping troop is selling popcorn to earn money for an upcoming camping trip. Each camper starts with a credit of $25 towards their sales, and each box of popcorn sells for $3.75. I have to write a function. ?f(b

Answer 1

Hello Esme,

 

If the question is to write a function that enables you to calculate the total sales value, in dollars, for the popcorn boxes sold then the function is as follows:

 

Every camper has $ 25 to begin with

Each popcorn box is sold for $3.75. Let's refer to the number of popcorn boxes sold as X.

 

Then the total value of money earned can be written as:

 

f(x) = 25 + 3.75X

 

where x is the popcorn boxes the camper was able to sell

 

So, for example, if 10 boxes were sold, then the camper earned 25 + 3.75 * 10 = $62.5
