8000 people attended a concert, ticket sales were $8 for adults and $4 for children. Total ticket sales was $52,000. How many adults and how many children attended. But show the work/formula.
------------------
Equations:
Quantity Equation: a + c = 8000
Value Equation::: 8a + 4c=52000 dollars
-----------------------------------------
Adjust the 1st equation for elimination:
8a + 8c = 8*8000
----
Subtract the Value Equation from that and solve for "c":
4c = 64000-52000
4c = 12000
c = 3000 (# of children's tickets sold)
---
Since a + c = 8000, a = 5000 (# of adult tickets sold)
