A baker bakes 5 loaves of bread an hour in one oven. He has 4 ovens. From Monday to Friday, he bakes for 5 hours, but on Saturday and Sunday, he only bakes for 2 hours. How many loaves of bread does the baker bake in 3 weeks?
In an hour, the baker bakes 5 x 4 = <T>multiply(5, 4)=20 loaves of bread.
From Monday to Friday, he bakes 5 x 20 = <T>multiply(5, 20)=100 loaves of bread per day.
From Monday to Friday, he bakes a total of 100 x 5 = <T>multiply(100, 5)=500 loaves of bread.
On Saturday and Sunday, he bakes 2 x 20 = <T>multiply(2, 20)=40 loaves of bread per day.
On Saturday and Sunday, he bakes a total of 40 x 2 = <T>multiply(40, 2)=80 loaves of bread.
In a week, he bakes 500 + 80 = <T>add(500, 80)=580 loaves of bread.
In 3 weeks, he bakes 580 x 3 = <T>multiply(580, 3)=1740 loaves of bread.
