Question

A consumer budgets $480 per month for transportation. She has determined that the cost of a round-trip train ride is $4 and the cost of each round-trip car ride (factoring in gas, oil, etc.) is $3.

Answer 1

It seems like you’re trying to figure out how many round-trip rides she can afford with her budget. Given that each round-trip train ride costs $4 and each round-trip car ride costs $3, we can calculate the maximum number of each type of trip she can take within her $480 budget.

For the train rides, we divide her total budget by the cost of a train ride:

4480​=120

So, she can afford 120 round-trip train rides.

For the car rides, we divide her total budget by the cost of a car ride:

3480​≈160

So, she can afford approximately 160 round-trip car rides.
