Question

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

(45, 30)
(30, 40)
(1, 45)
(1, 30)

Answer 1

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)**.
