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.
If we're going to use an inequality to solve this, then we'd probably be saying that 3.25 x ? >210. The 3.25 is the selling price per taco and the ? is the number of tacos that you sell. According to the equation, the number of tacos times the selling price has to be greater than 210, which are the expenses, in order to gain a profit. If we solve this, we simply divide 210 by 3.25. We will get an answer of 65. So we can conclude that if the taco business wants to have a profit, then they have to sell more than 65 tacos so that they can be able to cover their expenses.
