Quantitative Literacy Practice Exam 2025 – Comprehensive Preparation Guide

The method for finding the unit price when comparing two different quantities involves dividing the total price by the total quantity. This calculation gives you the cost per single unit of the product, which is essential for making comparisons between different items or quantities. By determining the unit price, you can more easily assess which option offers better value for your money.

For example, if you purchase a product costing $10 for 5 units, the unit price would be $10 divided by 5, which equals $2 per unit. This allows you to compare it directly with another product that might be priced differently or come in a different quantity.

Other methods mentioned, such as subtracting the total price from the smallest quantity or multiplying the total price by the total quantity, do not yield a meaningful unit price and are not viable methods for cost comparison. Finding the average price would provide a mean value but does not assist in determining the price per unit to evaluate value effectively.
