Question

7. Micronet dropped to $3.60 a share in October. What was the percent of decrease from July's per share price?
8. By the end of the year, Micronet's price rose back to $4.84 per share. What is the percent of increase from its original price?

Answer 1

You posted twice apparently...
5)
4.4+4.4x=6.82
4.4(1+x)=6.82
x=6.82/4.4-1=0.55=55%
6)
6.82-6.82x=5.56
6.82(1-x)=5.56
x=1-5.56/6.82=0.18=18%

I'll set up the last two for you, you can solve them yourself:
7)
5.56-5.56x=3.6
8)
4.4+4.4x=4.84

Answer 2

or can you really not solve these last two for x?
