Step-by-step reasoning process: If he sold a painting at a 10% loss, then he made a 10 / 100 * $40 = $4 loss on each painting. since he bought 10 paintings, the total loss he made from selling the paintings is 10 * $4 = $40. He also made a loss of 15 / 100 * 20 = $3 loss from selling each wooden toy. Since he bought 8 wooden toys, the total loss he made was 3 * 8 = $24. In total, Mr. Callen made a loss of $40 + $24 = $64 from the sales of the items.
