There are 4 co-workers and each of their meals is $12.00 so 4*12 = $<<4*12=48.00>>48.00
They order 2 appetizers at $6.00 each so 2*6 = $<<2*6=12.00>>12.00
The meals costs $48.00 and the appetizers costs $12.00 for a total of 48+12 = $<<48+12=60.00>>60.00
A 20% tip on the $60.00 order is .20*60 = $<<.20*60=12.00>>12.00
So the meal is $60.00, the tip is $12.00 and he adds a $5.00 rush for a total of 60+12+5 = $<<60+12+5=77.00>>77.00
