Regular tickets cost 34.50 and vip tickets cost 78.50 a total of 810 tickets were sold, and a total ticket sales were 29,045. The equation 34.50r + 78.50 (810-r)= 29,045 can be used to determine the number of regular tickets r sold to the concert. How many of each type of ticket were sold?

Number of regular tickets=785

Number of VIP tickets=25

Step-by-step explanation:

Step 1

Cost of Regular tickets=34.50

Costs VIP tickets =78.50

Total tickets sold =810

Cost of both rockets sold=29,045

Using the the given equation that 34.50r + 78.50 (810-r)= 29,045 to determine the number of regular tickets, we have that

Step 2---Solving

34.50r + 78.50 (810-r)= 29,045

34.50+63,585 - 78.50r=29,045

63585-29045=78.50r-34.50r

34,540=44r

r=34540/44

r=785=Number of regular tickets

Number of regular tickets+Number of VIP tickets =810

Number of VIP tickets=810-785=25

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.

the answer will be b x² +x-1
