1st step: You know we want to have 80 burgers in the end so now we know that we can make 20 burgers in one hour so we need to take 20 times 4. 4 * 20 = 80
2nd step: Since we times four for burgers now we have to times 4 to minutes.
3rd step: Now we are going to get 80 people so its 10 times 8 to get 80. 10 * 8 = 80
4th step: The more people cooking the less minutes so instead 240 times 8 we have to divided by 8. 240 / 8 = 30
