To find out how much money John spends in 15 days on rain (trains) and buses, we first need to calculate his daily spending.
John spends $3 for the rain and $2 for the bus each day, so his daily total spending is:
\[ 3 + 2 = 5 \text{ dollars per day} \]
Now, we can calculate his total spending over 15 days:
\[ 5 \text{ dollars/day} \times 15 \text{ days} = 75 \text{ dollars} \]
Next, we will determine the spending separately on trains and buses over these 15 days.
For the rain (trains): \[ 3 \text{ dollars/day} \times 15 \text{ days} = 45 \text{ dollars} \]
For the bus: \[ 2 \text{ dollars/day} \times 15 \text{ days} = 30 \text{ dollars} \]
Thus, after 15 days, John spends $45 on trains and $30 on buses. Therefore, the ordered pair representing how much money John spends in 15 days on trains and buses is:
\[ (45, 30) \]
The correct answer is (45, 30).
