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 tea were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Rice |
1 kg |
Lentils |
410 g |
Tea |
335 g |
Pasta |
200 g |
What is the difference between the total mass of pasta collected and the total mass of lentils 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 tea collected
= 96 - 24 - 40 - 16
= 16
(b)
Total mass of pasta collected
= 16 x 200
= 3200 g
Total mass of lentils collected
= 40 x 410
= 16400 g
Difference in mass between the total mass of pasta and the total mass of lentils collected
= 16400 - 3200
= 13200 g
1000 g = 1 kg
13200 g = 13200 ÷ 1000 = 13.2 kg
Answer(s): (a) 16; (b) 13.2 kg
