Question

Write and solve the system of equations below. Let a represent adults and let c represent children.

1,200 tickets were sold to the spring carnival. Adult tickets cost $6.00 and children's tickets cost $3.50. A total of $6,450 was collected. How many tickets of each kind were sold?
A.
a = 800, c = 400
B.
a = 900, c = 300
C.
a = 1,000, c = 200
D.
a = 1,100, c = 100

Answer 1

ok if u have above conditions .. u can have an equation ..
3.50*c+6*a=6450

Answer 2

and the other equation is a+c=1200

Answer 3

so it B ?

Answer 4

c=1100 ?

Answer 5

now u have two equations with just two variables .. put the value of variable a=1200-c in 1st equation and get the answer for c by eliminating a from equation

Answer 6

now put it in above equation and c what comes out for c
3.5*c+6(1200-c)=6450

Answer 7

now solve it and tell me the answer

Answer 8

B is answer man

Answer 9

im a girl dude ! and thats what i asked you .

Answer 10

can`t u solve it tell me .. i will show u all calculation then

Answer 11

ok buddy !! u got it ???

Answer 12

solve at least the last equation
u can see c=300 .. ok u should learn in this problem first to make simultaneous equations then solve them by elimination one variable as i did by eliminating a and got c.. then by putting c i got a too..
