A bulldozer is rented at $800 per day plus a charge per hour of use. The bulldozer was used for 5 hours on a day, and the total charge was $3000. Which equation can be used to find the charge x, in dollars, per hour of use?
800 + 5x = 3000
800x + 5 = 3000
800x + 5x = 3000
800 + 5 = 3000x

welshfella · Answer

800  is standard charge for the day then the charge per hour we can call x which must be multiplied by the number of hours to get this extra charge.  THen add the 800 dollars to this total  to get  an expression in Finally equate this to  3000.

@robtobey2 read the question again, did not ask to solve just how to set up the equation

mathmale · Answer

Hint:  The equation you want here has the "slope-intercept" form, and $800 is the value of the y-intercept.  You need to represent the SLOPE and the number of hours the tractor is used; the slope is a constant and the number of hours used is your independent variable.
