The bar graph shows the number of packets of different food collected in a donation drive.
- 13 of the total number of packets of food collected was rice. How many packets of tea were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Rice |
8 kg |
Milo |
325 g |
Tea |
410 g |
Oats |
500 g |
What is the difference between the total mass of oats collected and the total mass of milo collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 34
Total number of packets of food items collected
= 3 u
= 3 x 34
= 102
Number of packets of tea collected
= 102 - 34 - 34 - 20
= 14
(b)
Total mass of oats collected
= 20 x 500
= 10000 g
Total mass of milo collected
= 34 x 325
= 11050 g
Difference in mass between the total mass of oats and the total mass of milo collected
= 11050 - 10000
= 1050 g
1000 g = 1 kg
1050 g = 1050 ÷ 1000 = 1.05 kg
Answer(s): (a) 14; (b) 1.05 kg
