Practice Questions and Solutions

Let's put theory into practice, shall we? Here are a couple of sample questions to get you warmed up. Remember, the key is to read carefully, identify what's being asked, and then apply the appropriate formulas or techniques. Don't be afraid to use a calculator, and always double-check your answers!

Question 1:

A company's revenue increased from $500,000 to $625,000 in one year. What was the percentage increase in revenue?

Solution:

To calculate the percentage increase, we use the formula:

Percentage Increase = ((New Value - Old Value) / Old Value) * 100

Percentage Increase = (($625,000 - $500,000) / $500,000) * 100

Percentage Increase = ($125,000 / $500,000) * 100

Percentage Increase = 0.25 * 100

Percentage Increase = 25%

Therefore, the percentage increase in revenue was 25%.

Question 2:

A store sells a product for $80, which includes a 20% profit margin. What is the cost price of the product?

Solution:

Let the cost price be C. The selling price is the cost price plus the profit margin, which is 20% of the cost price.

Selling Price = Cost Price + (Profit Margin * Cost Price)

$80 = C + (0.20 * C)

$80 = 1.20 * C

C = $80 / 1.20

C ≈ $66.67

Therefore, the cost price of the product is approximately $66.67.
