The bar graph shows the number of packets of different food collected in a donation drive.
- 13 of the total number of packets of food collected was rice. 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 |
6 kg |
Milo |
260 g |
Dried Nuts |
405 g |
Biscuits |
300 g |
What is the difference between the total mass of biscuits collected and the total mass of milo collected? Give your answer in kg.
(a)
Number of packets of rice collected = 1 u
1 u = 26
Total number of packets of food items collected
= 3 u
= 3 x 26
= 78
Number of packets of dried nuts collected
= 78 - 26 - 24 - 16
= 12
(b)
Total mass of biscuits collected
= 16 x 300
= 4800 g
Total mass of milo collected
= 24 x 260
= 6240 g
Difference in mass between the total mass of biscuits and the total mass of milo collected
= 6240 - 4800
= 1440 g
1000 g = 1 kg
1440 g = 1440 ÷ 1000 = 1.44 kg
Answer(s): (a) 12; (b) 1.44 kg
