Basically a negative times a negative is always positive, but when a negative number is cubed (or raised to any odd exponent for that matter) the product will be negative.
I=PRT
R=percetnt in decimal form
x%=x/100
I=320
T=2
P=4000
320=(4000)(x/100)(2)
320=8000(x/100)
320=80x
divide both sides by 80
4=x
answer is 4%
It is 4/5. 20 and 25 have the GCF of 5. Divide both by 5. The answer is 4/5
