First you subtract 60-5 to see how much time you will have left to play.
60-5= 55
Then you divide 55/7 to see how many levels you can play for free.
55/7= I got 7.85 (rounded).
I hope its correct and sorry if its wrong! :)
Answer:
f(g(x)) = 12x + 1
Step-by-step explanation:
Step 1: Define functions
f(x) = 3x - 2
g(x) = 4x + 1
Step 2: Find f(g(x))
f(g(x)) = 3(4x + 1) - 2
f(g(x)) = 12x + 3 - 2
f(g(x)) = 12x + 1
103 represents how much money Victoria is depositing into the bank, or her principal.
The interest rate is 1.03, or 3%.
I'll do problem 13 to get you started.
The expression
is the same as 
Then we can do a bit of algebra like so to change that n into n-1

This is so we can get the expression in a(r)^(n-1) form
- a = 8/7 is the first term of the geometric sequence
- r = 2/7 is the common ratio
Note that -1 < 2/7 < 1, which satisfies the condition that -1 < r < 1. This means the infinite sum converges to some single finite value (rather than diverge to positive or negative infinity).
We'll plug those a and r values into the infinite geometric sum formula below
S = a/(1-r)
S = (8/7)/(1 - 2/7)
S = (8/7)/(5/7)
S = (8/7)*(7/5)
S = 8/5
S = 1.6
------------------------
Answer in fraction form = 8/5
Answer in decimal form = 1.6
