The Standard model sells for $235 and the Enhanced model sells for $305. If Yolanda sold a total of 11 units and took in $3,005, how many of the Enhanced model did she sell?
--------------------------
Equation:
Quantity:: s + e = 11
Value Eq::235s + 305e = 3005
--------------------------------------
Modify for elimination:
235s + 235e = 235*11
235s + 305e = 3005
------
Subtract and solve for "e"::
70e = 420
e = 6 (# of enhanced model's sold)
