If 113 people attend a concert and tickets for adults cost $4 while tickets for children cost $3.25 and total receipts for the concert was $395, how many of each went to the concert?
------
Quantity Eq:: a + c = 113 tickets
Value Eq:::: 4a +3.25c = 395 dollars
----------------------------------------
Modify for elimination:
4a +4c = 452
4a +3.25c = 395
--------
Subtract and solve for "c":
0.75c = 57
------
c = 76 (# of child tickets sold)
------
Solve for "a":
a + c = 113
a +76 = 113
a = 37 (# of adult tickets sold)
-------------------
