When Mary buys 8 widgets for 40.00. She adds 1.00 in enhancements to each widget and sells them for 9.00 each. What is marys estimated gross profit margin?

To calculate Mary's estimated gross profit margin, first determine her total cost: she spends $40.00 on 8 widgets and adds $1.00 in enhancements for each, totaling $48.00. She sells each widget for $9.00, earning $72.00 for all 8 ($9.00 x 8). Her gross profit is $72.00 - $48.00 = $24.00. The gross profit margin is calculated as (Gross Profit / Revenue) x 100, which is ($24.00 / $72.00) x 100 = 33.33%.
