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 fruits were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Rice |
1 kg |
Tea |
370 g |
Dried Fruits |
350 g |
Oats |
200 g |
What is the difference between the total mass of oats collected and the total mass of tea 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 fruits collected
= 80 - 16 - 22 - 30
= 12
(b)
Total mass of oats collected
= 30 x 200
= 6000 g
Total mass of tea collected
= 22 x 370
= 8140 g
Difference in mass between the total mass of oats and the total mass of tea collected
= 8140 - 6000
= 2140 g
1000 g = 1 kg
2140 g = 2140 ÷ 1000 = 2.14 kg
Answer(s): (a) 12; (b) 2.14 kg
