Call the price he paid for the shirt that gives him a 10% profit for $x$, then we have that 110% of $x$ is $880$. Correspondingly call the price of the he sold with a 20% lossfor $y$, then we have that 80% of $y$ is $880$. Written as formulas: $$ 1.1x=880 $$ and $$ 0.8y=880 $$ From that we find that $x=800$ and $y=1100$. So he spend a total of $1900$ and got a total income of 1760, so he has a total loss of $1900-1760=140$ which is $140/1900 \approx 0.0736$ or 7.36%.
