Question 706477
You have $160 for Tickets, and you want a total of 12 tickets. Some Could be weekday lawn seats which are $8 and the others need to be weekend lower box seats which $24. How many of each type of ticket can you buy? 
=====
Quantity Equation: D + E = 12 tickets
Value Equation::: 8D+24E = 160 dollars
-------
Multiply thru the Quantity Eq. by 8:
8D + 8E = 8*12
8D + 24E= 160
---
Subtract and solve for "E":
16E = 64
E = 4 (# of weekend tickets to buy)
-----
Solve for "D":
D + E = 12
D + 4 = 12
D = 8 (# of weekday tickets to buy)
