Eugene needs to rent a truck to move. A rental company charges $45 a day plus $0.25 per mile driven. His budget for the rental cannot be more than $120. How many miles can he drive within the budget?

Respuesta :

Well, you can first subtract 45 from 120, giving you 75. Now, you divide 75 by 0.25, which gives [tex] \boxed{300 miles} [/tex]

The pertinent inequality is $45 + ($0.25/mile)x ≤ $120.  Solving for x:

($0.25/mile)x ≤ ($120-$45).  This works out to 300 miles.

Eugene can drive up to 300 miles for $120.
