Question

Can someone explain how to find this answer please...thanks

Answer 1

To serve 350 students, you would need 350 servings. Each surving is 125g, so in total you would need

350 x 125 = 43,750g

43,750g is 43.75 kg. The cafeteria has 10 5-kg cans, so the cafeteria has

10 x 5 = 50 kg

50 is higher than 43.75, so the cafeteria will have enough to serve 350 students. 

Answer 2

Yes. Each can has 5000g. And since there are 10, the cafeteria has 50,000. You divide 50,000g by the serving size(125g) which is 400. So yes. The cafeteria has enough.
