Answer: price of advance ticket = $40
and price of same day ticket= $20
Step-by-step explanation:
let one advance ticket be x
let one same day ticket be y
The combined cost of one advance ticket and one same-day ticket is $60
so we have that
x + y = $60
For one performance, 40 advance tickets and 30 same-day tickets were sold of which the tota;l amount was $2,200
40x +30y= 2220
we have
x + y = $60... eqn 1
40x +30y= 2220... eqn 2
by substitution,
x+y = 60
y = 60-x
putting the value of y in equation 2
40x + 30(60-x) =2200
40x + 1800-30x=2200
40x-30x= 2200-1800
10x=400
x = 400/10 = 40
to get y
x+y =60
40 + y=60
y = 60-40 =20
Therefore price of advance ticket,x = $40
and price of same day ticket, y = $20
