I am new to the site but I need some math help. I am a business major and I am taking Business Finance. He wants us to do a bonus quiz to see how well our math skills are for the class. Well I cant seem to figure them out.

Someone plz help.

(1 + r)^2 = 10

(1+r)^2=10

(1+r)(1+r)=10

1+1r+1r+r^2

1+2r+r^2=10

2r+r^2=9

r^2=9-2x/x

r=9-2 =7?

60= [400/ (1 + r)^3]

If PV=110 r=.09 and t=4 find fv when fv= pv*(1+r)^t.

Solve for r directly when FVt=PVo *(1+r)^t
