Answer:
Step-by-step explanation:
As the options are not given in the question, lets find the amount spend in next 6 years and make a graph of it. I hope it helps
For year = 0:
Total spending = $12 billion
For year = 1:
Total spending is decreased by 30% as compared to year = 0
Find 30%:

Total spending = 12 - 3.6 = $8.4 billion
For year = 2:
Total spending is decreased by 30% as compared to year = 1
Find 30%:

Total spending = 8.4 - 2.5 = $5.9 billion
For year = 3:
Total spending is decreased by 30% as compared to year = 2
Find 30%:

Total spending = 5.9 - 1.77 = $4.13 billion
For year = 4:
Total spending is decreased by 30% as compared to year = 3
Find 30%:

Total spending = 4.13 - 1.24 = $2.89 billion
For year = 5:
Total spending is decreased by 30% as compared to year = 4
Find 30%:

Total spending = 2.89 - 0.87 = $2.02 billion
For year = 6:
Total spending is decreased by 30% as compared to year = 5
Find 30%:

Total spending = 2.02 - 0.60 = $1.42 billion
<h3>Graph:</h3>
x-axis = no. of year
y-axis = Total spending
Join the point to get the desired graph (see the picture)
