The bar graph shows the number of packets of different food collected in a donation drive.
- 15 of the total number of packets of food collected was rice. How many packets of dried nuts were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Rice |
10 kg |
Coffee |
430 g |
Dried Nuts |
260 g |
Milo |
200 g |
What is the difference between the total mass of milo collected and the total mass of coffee collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 16
Total number of packets of food items collected
= 5 u
= 5 x 16
= 80
Number of packets of dried nuts collected
= 80 - 16 - 26 - 14
= 24
(b)
Total mass of milo collected
= 14 x 200
= 2800 g
Total mass of coffee collected
= 26 x 430
= 11180 g
Difference in mass between the total mass of milo and the total mass of coffee collected
= 11180 - 2800
= 8380 g
1000 g = 1 kg
8380 g = 8380 ÷ 1000 = 8.38 kg
Answer(s): (a) 24; (b) 8.38 kg
