yes

670.80x0.14

anonymous · Answer

our instructor says we have to show the 5 steps

anonymous · Answer

if so, then you know 
$$\$670.80=.86P$$ and so $$P=670.80\div .86$$

anonymous · Answer

so it is A=p-rP

anonymous · Answer

reasoning that if you get a 14% discount, you pay 86% of the price

anonymous · Answer

right he said you subtract the 14 from 100

anonymous · Answer

by the distributive law 
$$P-rP=(1-r)P$$ so no need for the first step
just subtract $.14$ from $1$ or 14% from 100%

anonymous · Answer

so it will look like this  it would be 670.8-.86=.86P right?
