Solution
To analyze the problem shown in the image, let's go through the details provided:
-
Details from the Question:
- The number of people using public transport increased by 15% between Year 1 and Year 2.
- 50,000 more people commuted to work in Year 2 than in Year 1.
- 44,000 commuters used public transport in Year 2.
- 189,000 commuters used private transport in Year 1.
-
Objective: Arrange the commuting numbers for each mode of transport (public vs. private) for both years based on the given information.
-
Solution Steps:
-
Since the public transport users increased by 15% from Year 1 to Year 2, let the number of public transport commuters in Year 1 be .
- Then (because 44,000 commuters used public transport in Year 2).
- Solving for : So, approximately 38,261 people used public transport in Year 1.
-
Given there are 50,000 more commuters in Year 2 than in Year 1, the total commuters in Year 1 would be: If we denote the total commuters in Year 2 as , then: And:
-
-
Results Summary:
- Year 1:
- Public Transport: ~38,261
- Private Transport: 189,000
- Year 2:
- Public Transport: 44,000
- Private Transport: ~233,261
- Year 1:
