The bar graph shows the number of packets of different food collected in a donation drive.
- 14 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 |
6 kg |
| Milo |
355 g |
| Dried Nuts |
385 g |
| Dried Fruits |
200 g |
What is the difference between the total mass of dried fruits collected and the total mass of milo collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 26
Total number of packets of food items collected
= 4 u
= 4 x 26
= 104
Number of packets of dried nuts collected
= 104 - 26 - 26 - 34
= 18
(b)
Total mass of dried fruits collected
= 34 x 200
= 6800 g
Total mass of milo collected
= 26 x 355
= 9230 g
Difference in mass between the total mass of dried fruits and the total mass of milo collected
= 9230 - 6800
= 2430 g
1000 g = 1 kg
2430 g = 2430 ÷ 1000 = 2.43 kg
Answer(s): (a) 18; (b) 2.43 kg
