This question is solved using proportions, and doing this, it is found that Evan gets 5 Chinese yuans for every Australian dollar.
-----------------------------------------
- Evan budgeted $60 for the taxi ride.
- He went $15 over, thus, the taxi ride cost $75.
- In Chinese yuans, the cost was 375.
-----------------------------------------
75 dollars are worth 375 yuans. How much yuans is a dollar worth?
1 dollar - x yuans
75 dollars - 375 yuans
Applying cross multiplication:



Evan gets 5 Chinese yuans for every Australian dollar.
