20 percent
If you cross multiply 30 w/ 100 and then divide it by 150 you will get 20.
Answer:
200
Step-by-step explanation:
Let number of tickets sold before game be x while those at the gate be y
Total tickets sold are 600 hence x+y=600
Cost of tickets
Total amount collected is $700 hence
x+1.5y=700
x+y=600
x+1.5y=700
Subtracting equation 1 and 2
0.5y=100 hence y=200
Rx - st = r
Rx = r + st Add st to both sides
Rx - r = st Subtract r from both sides
(Rx - r)/t = s Divide t on both sides ( to isolate s)
