Answer:
C
Step-by-step explanation:
A geometric series will only converge if - 1 < r < 1
sum to infinity =
The nth term formula for a geometric series is
= a
where a is the first term and r the common ratio
The only summation with - 1 < r < 1 is C where r = - 0.2

Function: 
Amount earned for 10 hours of work: 
Step-by-step explanation:
Let be "x" the number of hours worked on a project and "y" the total amount Luigi charges for a project.
Based on the data given in the exercise, you can identify that:
- $140 is a fixed amount.
- For each hour worked on the project, Luigi charges $25. This can be expressed as:

Then, the total amount he charges for a project is the sum of $140 and
. This can be represented with the following function:

To calculate the amount of money earned for 10 hours of work, you must substitute
into the function and evaluate. Then:

19=1-5h-4h
19-1=-5h-4h
18=-9h
18/-9=h
h=-0.5
