You can put this solution on YOUR website! In one day, a software company sold 345 programs. The standard version sold for $19.50 each, while the deluxe version sold for $30 each. The company took in $8,334.00. How many of the standard versions of the software package were sold?
------------
Let number of standard sold be "x" ; value is 19.50x dollars
-----------------
# of delux sold is "345-x" ; value is 30(345-x) = 10350 - 30x dollars
-------------------
EQUATION:
value + value = 8334 dollars
19.50x + 10350 - 30x = 8334
-10.50x = -2016
x = 192 (# of standards sold)
345-192 = 153 (# of delux sold)
================
