Answer:

  3 days

Step-by-step explanation:

You can estimate the answer (correctly) by observing that 3 × 70 is 210. This is close enough to 232.85 that you know the number of rental days is not 2 or 4.

The equation for the number of days (d) is ...

  73.95d +11 = 232.85 . . . $73.95 per day plus an extra fee

  73.95d = 221.85 . . . . . . subtract 11

  d = 221.85/73.95 = 3 . . . . divide by the coefficient of d

The saw was rented for 3 days.
