Craig made 40 pizzas on their first day at work, while heather made four times that number, a total of 4*40= 160 pizzas.
Together, they made 160+40 = <<160+40=200>>200 pizzas on their first day.
On the second day, Craig made 60 more pizzas than his first day at work, which totals 60+40 = <<60+40=100>>100 pizzas.
On the same day, Heather made 20 fewer pizzas than Craig, a total of 100-20 = <<100-20=80>>80 pizzas.
Together, they made 80+100 = <<80+100=180>>180 pizzas on the second day.
In the two days, the two of them made a total of 180 +200 = <<180+200=380>>380 pizzas.
