At the city museum, child admission is $5.50 and adult admission is $8.60. On Tuesday, 139 tickets were sold for a total sales of $1028.00. How many adult tickets were sold that day?
-----
Quantity Equation:: c + a = 139 tickets
Value Equation:: 5.5c+8.6a = 1028
-----
Modify for elimination::
55c + 55a = 55*139
55c + 86a = 10280
----
Subtract and solve for "a"::
31a = 2635
a = 85 (# of adult tickets sold)
