Choosing the Class Trip
The Grade 5 class has 48 students and 3 teachers. They are choosing a one-day trip. The class fund has Rs. 4,000. Each student can pay up to Rs. 50 extra. Teachers enter free. Three options are on the table. The zoo is 12 km away: entry is Rs. 60 per student, the bus costs Rs. 3,000, and the weather forecast says an 80% chance of heavy rain; the zoo has only a small shelter. The museum is 8 km away: entry is Rs. 40 per student, the bus costs Rs. 2,500, it is indoors, and a guided tour takes 45 minutes. The botanical garden is 15 km away: entry is Rs. 30 per student, the bus costs Rs. 3,500, it is outdoors, and there are few shelters. The teacher asks the class to choose using cost, safety and learning value, not just the lowest price.
1. Calculate the total cost of each trip and the total money available. Which trips can the class afford?
Read the worked answer
Money available:
Class fund Rs. 4,000 + students' extra money (48 × Rs. 50 = Rs. 2,400) = Rs. 6,400.
Zoo:
Entry = 48 × Rs. 60 = Rs. 2,880.
Bus = Rs. 3,000.
Total = Rs. 5,880.
Museum:
Entry = 48 × Rs. 40 = Rs. 1,920.
Bus = Rs. 2,500.
Total = Rs. 4,420.
Botanical garden:
Entry = 48 × Rs. 30 = Rs. 1,440.
Bus = Rs. 3,500.
Total = Rs. 4,940.
Comparison: All three trips cost less than Rs. 6,400, so the class can afford any one of them. The museum is the cheapest, the zoo is the most expensive, and the garden is in between. Cost alone does not decide the choice.
2. Which trip should the class choose? Give two reasons and one disadvantage of your choice.

Best choice: the museum.
Reason 1 – Safety in the forecast rain: The forecast says an 80% chance of heavy rain. The museum is indoors, so the trip can go ahead without children standing in the rain. The zoo has only a small shelter, and the garden has few shelters, so both would be uncomfortable and possibly unsafe in heavy rain.
Reason 2 – Learning value and cost: The museum costs Rs. 4,420, the lowest total, and includes a 45-minute guided tour. That gives the class a structured learning activity and leaves Rs. 1,980 from the available money for emergencies or another small activity.
Disadvantage: The museum is not outdoors, so the class gets less exercise and less chance to observe plants and animals in the open. The teacher would need to plan a short outdoor break or a follow-up activity.
Judgement: The zoo might be more exciting, but an 80% rain forecast makes it a risky choice. The museum is the safer and more reliable plan for this particular day.
3. If the museum is closed on the trip day, choose between the zoo and the garden. Explain your choice with one safety point and one cost point.

Choice: the zoo, if the rain is not too heavy.
Safety point: The zoo has a small shelter, while the garden has few shelters. In a sudden shower, the class can move to the zoo shelter. At the garden, the class may be caught in the open. This matters more than saving money when 48 children are on the move.
Cost point: The zoo costs Rs. 5,880 and the garden costs Rs. 4,940. The garden is Rs. 940 cheaper, but the class can still afford the zoo with the Rs. 6,400 available. Paying more is reasonable here because the shelter reduces the safety risk.
Caveat: If the forecast changes to very heavy rain or strong wind, neither outdoor trip is wise. The class should then postpone or choose another indoor place, even if it costs a little more.
