Understanding Average Cost Calculation

The video tutorial explains how to calculate the average cost of shoes purchased by Juan and Maria. Juan bought shoes for $50 each, and Maria for $60 each. The ratio of shoes bought by Juan to Maria is 3:2. Assuming a total of five pairs were purchased, Juan bought three pairs and Maria two. The total cost is calculated by multiplying the number of pairs by their respective prices, resulting in $270. Dividing this total by the number of pairs gives an average cost of $54 per pair.
