A car can be rented for $50 per week plus $0.75 per milo. How many miles can be driven if you have at most $140 to spend for wookly transportation?

120 Miles

Step-by-step explanation:

We start with $140.

The initial payment is $50.  

$140 - $50 = $90

We now have $90 dollars to spend on miles.

$90/$0.75 per mil = 120 Miles

Using the remaining $90 we can drive 120 miles in a week.
