Question

John pays $3 for the train and $2 for the bus each day. Which ordered pair represents how much money John spends in 15 days on trains and buses?

A) (45, 30)
B) (30, 40)
C) (1, 45)
D) (1, 30)

Answer 1

To determine how much John spends on trains and buses over 15 days, we can calculate the total cost for each mode of transportation separately.

1. **Cost of the train:**
- John spends $3 each day for the train.
- For 15 days, the total cost for the train is:
\[
3 \, \text{dollars/day} \times 15 \, \text{days} = 45 \, \text{dollars}
\]

2. **Cost of the bus:**
- John spends $2 each day for the bus.
- For 15 days, the total cost for the bus is:
\[
2 \, \text{dollars/day} \times 15 \, \text{days} = 30 \, \text{dollars}
\]

Now we have the total spent on trains and buses:
- Total spent on trains: $45
- Total spent on buses: $30

This gives us the ordered pair representing how much money John spends in 15 days on trains and buses:
\[
(45, 30)
\]

Thus, the correct answer is **A) (45, 30)**.
