Question

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)=

Answer 1

Answer:

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

Answer 2

Answer:

$E(n)=75000 \times 2^n$

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 $2^n times$

So, her earning will be : $75000 \times 2^n$

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

So, the function becomes :

$E(n)=75000 \times 2^n$

Hence a function that gives Mapiyas cumulative earnings E(n), in dollars when she has written n sequel's  is  $E(n)=75000 \times 2^n$
