Mapiya writes a series of novels. she earned $75000 for the first book, and her cumulative earnings double with each sequel that she writes. write a function that gives mapiyas cumulative earnings e(n), in dollars when she has written n sequel's e(n)=

E(n)=$75000 *2^n

Step-by-step explanation:

If we start with the initial value,   $75,000  , and keep multiplying by   2  , this function gives us Mapiya's cumulative earnings when she has written   n   sequels.

E(n)=75000⋅2

n

Step-by-step explanation:

We are given that she earned $75000 for the first book.

We are also given that her cumulative earnings double with each sequel that she writes.

Let she has written n sequel's

Now since we are given that her cumulative earnings double with each sequel

So, her initial earning will be

So, her earning will be :

Now we are given that cumulative earnings is denoted by E(n)

So, the function becomes :

Hence a function that gives Mapiyas cumulative earnings E(n), in dollars when she has written n sequel's  is  

definitely a. the others have almost all data points on one side of the line.
