Daniel and Sophia work at a furniture store. Daniel is paid $220 per week plus 8.5%
of his total sales in dollars, x, which can be represented by g(x) = 220 + 0.085x.
Sophia is paid $517 per week plus 3% of her total sales in dollars, x, which can be
represented by f(x) = 517 + 0.03x. Determine the value of x, in dollars, that will
make their weekly pay the same.

step-by-step explanation:

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.
