This problem is suitable for students who have studied rate. However, any students who can do the basic operations with money / decimals have the prerequisites to solve this problem.
This problem is about bus and train fares in London.
Each train ride costs £3.80 but the maximum that is charged each day is £10.60.
Each bus ride costs £1.40 but the maximum that is charged each day is £4.40.
If a customer buys the weekly pass, which costs £43.60, he can ride the train and bus as many times as he wishes for seven days.
The amount is deducted from a fare card called Oyster Card.
(a) John took two train rides on Monday.
Find the amount he had to pay for the train rides.
(b) Kimi took three train rides on Monday.
Find the amount she had to pay for the train rides.
(c) This week I will take four bus rides and two train rides each day for five days.
Should I buy the weekly pass?
