As a salesperson you get$30/day and $4.80 per each sale you make. If you want to make at least $106 in
one day how many sales would you need to make?

16 sales

Step-by-step explanation:

Create an equation like so:

30 + 4.80x = 106
Where x is the number of sales

4.80x = 76

x = 76/4.80

x = 15.8333333

x = 16
Therefore 16 sales because we cannot have a fraction of a sale.

you probably already have the answer but anyways it's b. 15.0

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.
