Select the correct answer. a moving company charges $115 to rent a truck for a three-day period, plus an additional $0.83 for each mile driven. the average cost per mile for a three-day period is given by the rational expression , where x is the number of miles driven during the rental period. what does the numerator of the rational expression represent?

The numerator represents the total cost for renting the truck over a three-day period.

Step-by-step explanation:

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116
