Christine went shopping and bought each of her nine nephews a gift, either a video costing $14.95 or a cd costing $16.88. she spent $142.27 on the gifts. how many videos and how many cds did she buy?

V + c = 9v = 9 - c
14.95v + 16.88c = 142.27

14.95(9 - c) + 16.88c = 142.27
134.55 - 14.95c + 16.88c = 142.27
-14.95c + 16.88c = 142.27 - 134.55
1.93c = 7.72
c = 7.72 / 1.93
c = 4 <=== there were 4 CD's

v + c = 9
v + 4 = 9
v = 9 - 4
v = 5 <=== there were 5 videos
