Question

Target is advertising a 55-inch television for $275.00. A 75-inch television of the same brand costs $379.00. Which is the better buy? Take into account that the smallest television of this brand is 13-inches. How do you know?

Answer 1

The 55-inch television is a better buy

Explanation:

The best way to determine the better buy would be to determine the actual value provided from each television in terms of cost per square inch of the television screen. Therefore, in order to calculate this, we would need to divide the total cost of each television by their respective screen size.

Television 1: $275.00 / 55 = $5 per square inch

Television 2: $379.00 / 75 = $5.05 per square inch

Therefore, based on these values we would say that The 55-inch television is a better buy since you are saving roughly $0.05 per square inch on that purchase when compared to the 75-inch screen. This method also works for any size TV including the 13-inch.
