Answer:
12 inches
Step-by-step explanation:
A=1/2bh
30=1/2b5
(30*2)/5=b
B=12
.05c+.3s=10.25, c+s=100, c=100-s (c is for cards that don't sing and s is for those that do :P)
.05c+.3s=10.25 and c=100-s makes the equation become:
.05(100-s)+.3s=10.25
5-.05s+.3s=10.25
.25s=5.25
s=21, and since c=100-s
c=79
So she bought 21 of the more expensive singing cards...
