The spreadsheet is missing, so i have attached it.
Answer:
Option A - $295
Step-by-step explanation:
From the spreadsheet, net pay = $2300 and interest earned on savings = $20
Therefore, her total income = $2300 + $20 = $2320
Now,from the spreadsheet, total expenses = 800 + 120 + 90 + 45 + 95 + 80 + 275 + 520 = $2025
Now, net cash flow = Total income - Total expenses
Net cash flow = $2320 - $2025
Net cash flow = $295
we know that
A relationship between two variables, x, and y, represent a proportional variation if it can be expressed in the form y/x=k or y=kx
so
That means it's the equation of a line passing through the origin.
case a) and case d) are discarded because the line does not pass through the origin
<u>case b) we have</u>
for x=2 y=4
y/x=k-------> 4/2=2------> k=2
y=2x-------> in this case the value of y is two times the value of x
<u>case c) we have</u>
for x=4 y=2
y/x=k-------> 2/4=1/2------> k=(1/2)
y=(1/2)x-------> in this case the value of y is one-half of the value of x
therefore
the solution is the case c) see the attached figure
