Step-by-step explanation:
Let
denote the first term of this geometric series, and let
denote the common ratio of this geometric series.
The first five terms of this series would be:
First equation:
.
Second equation:
.
Rewrite and simplify the first equation.
.
Therefore, the first equation becomes:
..
Similarly, rewrite and simplify the second equation:
.
Therefore, the second equation becomes:
.
Take the quotient between these two equations:

Answer:
3t + 1,023
Step-by-step explanation:
The computation is shown below:
As a tutor it is $14 per hour
As a waitress it is $11 per hour
Total number of hours worked is 93
Now let us assume the number of hours worked as a tutor is t
So as a waiter is 93 - t
Now the equation is
= $14(t) + $11(93 - t)
= 14t + 1,023 - 11t
= 3t + 1,023
