Question

VII. Word Problems: 1, At a party for 300 people, 15 bags of ice are needed in a hotel. How many bags are needed if there is a function for 120 people in this hotel? ( 2 marks)

Answer 1

Proportions

We're given:

• 300 people : 15 ice bags
• 120 people : x ice bags

Given the above, we can write the following equation:

`(15)/(300)=(x)/(120)`

Isolate x:

`x=6`

Therefore, 6 ice bags are needed for 120 people.
