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 oats were collected?
- The table shows the mass of each packet of food.
| Food Items |
Mass of each packet |
| Rice |
8 kg |
| Milo |
460 g |
| Oats |
490 g |
| Tea |
200 g |
What is the difference between the total mass of tea collected and the total mass of milo collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 24
Total number of packets of food items collected
= 4 u
= 4 x 24
= 96
Number of packets of oats collected
= 96 - 24 - 38 - 14
= 20
(b)
Total mass of tea collected
= 14 x 200
= 2800 g
Total mass of milo collected
= 38 x 460
= 17480 g
Difference in mass between the total mass of tea and the total mass of milo collected
= 17480 - 2800
= 14680 g
1000 g = 1 kg
14680 g = 14680 ÷ 1000 = 14.68 kg
Answer(s): (a) 20; (b) 14.68 kg
