Question 1073269
if each bag of rice serves 3 people, then each person is served by 1/3 of a bag of rice.


1/3 * p + 4 = 8


subtract 4 from both sides of this equation to get 1/3 * p = 4


multiply both sides of this equation by 3 to get p = 12.


you can serve 12 people with 8 bags of rice.


take 4 away and keep them for safe measure.


you will be using 4 bags of rice.


since each bag of rice can serve 3 people, 4 * 3 = 12 people that can be served by those 4 bags of rice.
