can you please help show me how to solve this equation and what formula to use to do it Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! There are two variables
price for adult and cost for child
Let price for adult be x
and price for child be y
Group I
10 adults and 8 children
they paid $136
write the equation
10x+8y=136...................(1)
Group II
17x+2y=150...................(2)
solve the two equations by elimination method
multiply equation (2) by -4
we get
-68x-8y=-600...................(3)
add equation (1) & (3)
we get
-58x=-464
/-58
x= -464/-58
x= 8
$ 8 for adult
Plug x in the equation (1)
10x+8y=136
10*8 + 8y=136
80+8y=136
8y=136-80
8y=56
/8
y = 7
$7 price for child
