Complete question:
write a function that gives mapiyas cumulative earnings E(n), in dollars when she has written n sequel's
Step-by-step explanation:
According to the question, she earned $75000 for the first book.
Also,We are given that her cumulative earnings double with each sequel that she writes.
Assuming 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
times
So, her earning will be : ![75000 \times 2^n](https://tex.z-dn.net/?f=75000%20%5Ctimes%202%5En)
Now we are given that cumulative earnings is denoted by E(n)
So, the function becomes :![E(n)=75000 \times 2^n](https://tex.z-dn.net/?f=E%28n%29%3D75000%20%5Ctimes%202%5En)
Hence a function that gives Mapiya's cumulative earnings E(n), in dollars when she has written n sequel's is ![E(n)=75000 \times 2^n](https://tex.z-dn.net/?f=E%28n%29%3D75000%20%5Ctimes%202%5En)
