please help

Answer 1

1200 miles

Explanation:

You want to know how far you can drive in a week on a budget of 300 in a rental car that costs 120 per week and 0.15 per mile.

Solution

After you pay the 120 weekly charge from your budget of 300, you have ...

300 -120 = 180

left to pay the mileage charges.

If each mile costs 0.15, then you can afford to pay for ...

180/(0.15/mi) = 1200 mi

You can travel 1200 miles in a week for 300.

Additional comment

If you like, you can write an equation for the cost (c) as a function of the miles driven (m):

c = 120 +0.15m

Equating that to your budget of 300, you can solve for m:

300 = 120 +0.15m

180 = 0.15m . . . . . . . . . . subtract 120

180/0.15 = 1200 = m . . . . . divide by 0.15

This solution should look a lot like the one described above.
