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 noodles. How many packets of flour were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Flour |
8 kg |
Milo |
370 g |
Noodles |
375 g |
Coffee |
200 g |
What is the difference between the total mass of milo collected and the total mass of coffee collected? Give your answer in kg.
(a)
Number of packets of noodles collected= 1 u
1 u = 14
Total number of packets of food items collected
= 5 u
= 5 x 14
= 70
Number of packets of flour collected
= 70 - 10 - 14 - 22
= 24
(b)
Total mass of milo collected
= 10 x 370
= 3700 g
Total mass of coffee collected
= 22 x 200
= 4400 g
Difference between the total mass of milo and the total mass of coffee collected
= 4400 - 3700
= 700 g
1000 g = 1 kg
700 g = 700 ÷ 1000 = 0.7 kg
Answer(s): (a) 24; (b) 0.7 kg
