Susan Delaney analyzes product profitability of one of her clients using the following data:

	2013	2014	2015
Overhead costs	110,000	120,000	100,000
Direct labor	25,000	30,000	20,000

She is particularly interested in profitability of Product 1, which had its sales price and costs per unit unchanged during these years at:

	Product1
Sales price (per unit)	118
Direct material cost	19
Direct labor cost	10

For financial reporting purposes, overhead is allocated to products based on direct labor costs using actual overhead rates that vary from year to year. The net operating profit margin is defined as sales minus full product costs (labor, material, and allocated overhead costs). Here it means dollars of profit per product, NOT profit margin as a percentage of sales. What was the net operating profit margin of Product 1 in 2015?
