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 coffee. How many packets of rice were collected?
- The table shows the mass of each packet of food.
Food Items |
Mass of each packet |
Rice |
5 kg |
Tea |
275 g |
Coffee |
320 g |
Dried Fruits |
300 g |
What is the difference between the total mass of tea collected and the total mass of dried fruits collected? Give your answer in kg.
(a)
Number of packets of coffee collected= 1 u
1 u = 18
Total number of packets of food items collected
= 6 u
= 6 x 18
= 108
Number of packets of rice collected
= 108 - 34 - 18 - 32
= 24
(b)
Total mass of tea collected
= 34 x 275
= 9350 g
Total mass of dried fruits collected
= 32 x 300
= 9600 g
Difference between the total mass of tea and the total mass of dried fruits collected
= 9600 - 9350
= 250 g
1000 g = 1 kg
250 g = 250 ÷ 1000 = 0.25 kg
Answer(s): (a) 24; (b) 0.25 kg
