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 pasta. How many packets of flour were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Flour |
6 kg |
Cereals |
265 g |
Pasta |
305 g |
Coffee |
200 g |
What is the difference between the total mass of cereals collected and the total mass of coffee collected? Give your answer in kg.
(a)
Number of packets of pasta collected= 1 u
1 u = 16
Total number of packets of food items collected
= 6 u
= 6 x 16
= 96
Number of packets of flour collected
= 96 - 16 - 16 - 34
= 30
(b)
Total mass of cereals collected
= 16 x 265
= 4240 g
Total mass of coffee collected
= 34 x 200
= 6800 g
Difference between the total mass of cereals and the total mass of coffee collected
= 6800 - 4240
= 2560 g
1000 g = 1 kg
2560 g = 2560 ÷ 1000 = 2.56 kg
Answer(s): (a) 30; (b) 2.56 kg
