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 flour. How many packets of noodles were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Flour |
8 kg |
Oats |
455 g |
Noodles |
380 g |
Milo |
300 g |
What is the difference between the total mass of milo collected and the total mass of oats collected? Give your answer in kg.
(a)
Number of packets of flour collected = 1 u
1 u = 16
Total number of packets of food items collected
= 6 u
= 6 x 16
= 96
Number of packets of noodles collected
= 96 - 16 - 34 - 18
= 28
(b)
Total mass of milo collected
= 18 x 300
= 5400 g
Total mass of oats collected
= 34 x 455
= 15470 g
Difference in mass between the total mass of milo and the total mass of oats collected
= 15470 - 5400
= 10070 g
1000 g = 1 kg
10070 g = 10070 ÷ 1000 = 10.07 kg
Answer(s): (a) 28; (b) 10.07 kg
