Answer:
Grandstand ticket = $380.
General admission ticket = $220
Step-by-step explanation:
Let the price of One grandstand ticket be X dollars and the price of One general admission ticket be Y dollars.
Then according to question,
6X + 2 Y = 2720 -(1)
Also,
4X + 4 Y = 2400 -(2)
Simplifying second equation we get ,
X + Y = 600 , Thus , X = 600 - Y .
Put X = 600 - Y in Equation 1.
So,
3600 - 6Y + 2Y = 2720
4Y = 880
Y = $220
Thus, X = 600 - 220 = $380.
So,
Cost of grandstand ticket is $380 and cost of general admission ticket is $220.
Answer:
