You can put this solution on YOUR website! Christine went shopping and bought each of her ten nephews a gift,either a video costing $14.95 or a CD costing $16.88 She spent $161.08 on the gifts. How many videos and how many CD's did she buy?
------
Equations:
Quantity:: v + c = 10
Value:: 14.95v + 16.88c = 161.08
---------------------
Modify::
1495v + 1495c = 14950
1495v + 1688c = 16108
-------------------------------
Subtract and solve for "c":
-------
193c = 1158
c = 6 (# of CD's bought)
----
v = 10-6 = 4 (# of video's bought)
----------
