Flour |
7 kg |
Tea |

Pasta |
415 g |
Milo |
500 g |
What is the difference between the total mass of tea collected and the total mass of milo collected? Give your answer in kg.
(a)
Number of packets of pasta collected= 1 u
1 u = 30
Total number of packets of food items collected
= 3 u
= 3 x 30
= 90
Number of packets of flour collected
= 90 - 14 - 30 - 20
= 26
(b)
Total mass of tea collected
= 14 x 380
= 5320 g
Total mass of milo collected
= 20 x 500
= 10000 g
Difference between the total mass of tea and the total mass of milo collected
= 10000 - 5320
= 4680 g
1000 g = 1 kg
4680 g = 4680 ÷ 1000 = 4.68 kg
Answer(s): (a) 26; (b) 4.68 kg
