A line graph depicts quarterly sales (in $M) for a retail chain over four years (16 quarters). The graph indicates a consistent growth trend, with an average increase of $5M per quarter over the last eight quarters. Sales for Q4 of Year 4 were $120M. Based on this observed trend, what is the *most reasonable* projection for the chain's sales in Q1 of Year 5?
✓ Correct Answer: Option C
Given the Q4 Year 4 sales were $120M and the average quarterly increase is $5M, the most reasonable projection for Q1 Year 5 is $120M + $5M = $125M.
