The question is
A retailer sells widgets for $\$120$ each, which is $20\%$ more than they cost from wholesales. How much gross profit does the retailer earn after selling $8 widgets
\$ 140$
$\$ 148
\$ 160$
$\$ 172
\$ 176$
After some calculations, I get $\$192$ which in not in the answer list.
I dont know. Please correct me if I have just made a mistake in the middle.
Thanks
