Liberty bought a make-your-own salad when she went out to lunch at a restaurant. The salad cost $4, plus $0.85 for each salad topping. Liberty spent $9.95 on the salad. Which equation can be used to find t, the number of toppings that Liberty ordered on her salad? A.
4.00 + 0.85t = 9.95

B.
0.85 + 4.00t = 9.95

C.
4.00 x 0.85t = 9.95

D.
0.85 x 4.00t = 9.95

4.00+0.85t=9.95

Step-by-step explanation:

4+0.85t=9.95

-4             -4

0.85t=5.95

/0.85   /0.85

t=7

your answer would be 12

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.
