The bar graph shows the number of packets of different food collected in a donation drive.
- 16 of the total number of packets of food collected was milo. 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 |
3 kg |
Milo |
375 g |
Coffee |
465 g |
Dried Nuts |
200 g |
What is the difference between the total mass of coffee collected and the total mass of rice collected? Give your answer in kg.
(a)
Number of packets of milo collected = 1 u
1 u = 16
Total number of packets of food items collected
= 6 u
= 6 x 16
= 96
Number of packets of dried nuts collected
= 96 - 24 - 16 - 28
= 28
(b)
1 kg = 1000 g
3 kg = 3 x 1000 = 3000
Total mass of rice collected
= 24 x 3000
= 72000 g
Total mass of coffee collected
= 28 x 465
= 13020 g
Difference between the total mass of coffee and the total mass of rice collected
= 72000 - 13020
= 58980 g
1000 g = 1 kg
58980 g = 58980 ÷ 1000 = 58.98 kg
Answer(s): (a) 28; (b) 58.98 kg
