Answer:
Each students provides 13 pounds of meal
Step-by-step explanation:
Total students in Ms. Lee class = 220
Total pounds of food collected = 2,860
how many meals did each student provide?
Meals provided by each student = Total pounds of food collected / total number of students
= 2,860 / 220
= 13 pounds
Each students provides 13 pounds of meal
Note: 1.2 pounds of food equals one meal
1.2 pounds : 1 meal = 13 pounds : x meals
1.2/1 = 13/x
1.2 * x = 1 * 13
1.2x = 13
x = 13 / 1.2
= 10.83 meals
Approximately 11 meals to the nearest number
Note:1 kilogram is 2.2 pounds
1 kg : 2.2 pounds = x kg : 13 pounds
1/2.2 = x / 13
1 * 13 = 2.2 * x
13 = 2.2x
x = 13/2.2
= 5.91 kilogram
Approximately x = 6 kilograms
the answer is B because to get the total cost, first divide 450 by 50. This gives us 9. We then multiply 9 by $600 to get a total of $5400.
