Quarter 1 sales for an automobile manufacturer were $180 million. If the quarter 1 seasonal index was 1.8, what is the estimate of annual sales for this firm?
A
$400 million
B
$180 million
C
$720 million
D
$100 million
Explanation:
Explanation:
A seasonal index of 1.8 means that Quarter 1 sales are 80% above the average quarterly sales (since an index of 1.0 represents the average).
Step 1: Calculate average quarterly sales
$180 million$180 million ÷ 1.8 = $100 millionStep 2: Calculate annual sales estimate
$100 million × 4 = $400 millionTherefore, the correct answer is $400 million.
The provided explanation in the text confirms this calculation:
"An index of 1.8 means that quarter 1 sales are 80% above the norm (average). Thus, each quarter has average sales worth $180,000,000 / 1.8 = $100,000,000. Therefore, the annual estimate = 4 * Quarter average = 4 * $100,000,000 = $400,000,000."
