This is the answer I gave, it reads it correct but doesnt make much sence haha.
so we know that a1 is 40,000 because it is what she makes her first year. next we know that it increases by 1.03 of last years salary every year. the rest I havent really figured out yet.
next i will put what edjenuity would like you to have in your answer,
The partial sum that models the situation is Sn=a1(1 – rn)/(1 – r).
n = number of years Mia works this job
an = Mia’s salary during her nth year
Sn = total amount Mia earns after n years
r = percent increase, represented as a decimal, plus 1, because the total salary is needed and not just the amount of each increase
With Combination, There are the 98280 ways by which we place books on the shelf.
According to the statement
We have to find that the number of ways can by which place books on the shelf.
So, For this purpose, we know that the
A combination is a mathematical technique that determines the number of possible arrangements in a collection of items where the order of the selection does not matter.
From the given information:
The library has 28 science fiction books. Each shelf holds 5 books
Then
apply the combination,
Then
C(n,r) = C(28,5)
after solving it become
C(28,5) = 28! /(5!(28-5)!)
And
C(28,5) = 28! /(5!(23)!)
Then after rearranging the terms and solving the value becomes
C(28,5) = 98280.
So, With Combination, There are the 98280 ways by which we place books on the shelf.

You divide by 2 until you can't divide by 2 anymore.
Hope this helps.
Adults: $22
Children: $22 - $5 = $17
22a + 17c = t
22(12) + 17(15) = t
264 + 255 = $519
The total cost of admission is $519.
Hope this helped!
I think the answer would be 10.5
