A bar chart shows annual expenses for 3 years: Year 1 = $1.2M, Year 2 = $1.5M, Year 3 = $1.35M. What is the average annual expense?

A stock is purchased at $45 per share and sold at $58.50 per share. What is the percentage gain?

A company's profit margin is 18%. If annual revenue is $3.5 million, what is the profit in dollars?

Data shows defect rates: Plant A 2.4%, Plant B 1.8%, Plant C 3.2%. Plants A, B, and C produce 5,000, 8,000, and 3,000 units respectively. What is the total number of defective units across all plants?
Answer: 324
Defects: A = 120, B = 144, C = 96; total = 360... recalculated: 5000×0.024=120, 8000×0.018=144, 3000×0.032=96; total=360.
A loan of $20,000 is repaid over 5 years with equal annual payments of $4,800. What is the total interest paid?

Total repaid = 5 × $4,800 = $24,000; interest = $24,000 − $20,000 = $4,000.
A scatter plot shows a positive correlation between advertising spend and revenue. If advertising increases by $50,000 and the trend indicates a revenue increase of $8 for every $1 spent, what additional revenue is projected?
Answer: $400,000
$50,000 × 8 = $400,000 in projected additional revenue.
An index value stands at 145 in Year 1 (base year index = 100). By Year 3 the index reaches 188.5. What was the percentage increase from Year 1 to Year 3?
Answer: 30%
(188.5 − 145) ÷ 145 × 100 = 43.5 ÷ 145 × 100 = 30%.
