I got a profit of #color(blue)($1560)#

Explanation:

Noting that half of #156# is #78#

#{: (color(white)("xxxxxxxx"),,ul("Cost"),,"|",ul("Sales"),,), ("num. of units:","||",156,,"|",78,,), ("unit value:","||",ul($32),$4992,"|",ul($45),$3510,), ("num. of units:","||",,,"|",78,,), ("unit value:","||",,,"|",ul($39),ul($3042),$6552) :}#

#"Profit" = "Total sales value" - "Total cost"#
#color(white)("XXxX")=$6552-$4992=color(blue)($1560)#
