Part a: maci made $170 grooming dogs one day with her mobile dog grooming business. she charges $60 per appointment and earned $50 in tips. write an equation to represent this situation. (4 points)
part b: logan made a profit of $210.00 as a mobile groomer. he charged $75.00 per appointment and received $35.00 in tips, but also had to pay a rental fee for the truck at $10.00 per appointment. write an equation to represent this situation. (4 points)
part c: explain how the equations from part a and part b differ. (2 points)

i think the answer is b.

step-by-step explanation:

not 100% sure though.

solution:

the given function is ,

      =

the three roots of this quadratic function is , 0 ,8 and 10.all the roots are real and rational.

if a quadratic equation is of the form ,

sum of the roots = a + b +c= 0+8+10=18=  

product of roots taken two at a time = a b + b c+ c a = 0+80+0=80 =  

product of roots = a b c = 0=  

there are 11 doors in a hall starting from 0 to 11.the entry in the hall is permitted through gate number 0 and exit is allowed through only gate number 8 and 10.so, three roots(0,8,10) of quadratic function is given by entry and exit route of this hall.
