Answer 1

D right?

Answer 2

@ShadowLegendX please :3

Answer 3

Let me work it out

Answer 4

\[C = P(1 -d)\]

Distribute

\[C = P - Pd\]

Subtract P from both sides

\[C - P = -Pd\]

Divide the entire equation by -P to isolate d, and change the negative sign to a positive.

\[-\frac{ C }{ P } + 1 = d\]

Answer 5

We get 1 from,

\[\frac{ -P }{ -P} = 1\]

Answer 6

Let me know if you understand it

Answer 7

Okay so it's A then
Because you divide by p then minus 1

Answer 8

You subtract P, then divide by -P

This converts -P to -P/-P to +1

Answer 9

Okay so then it is B

Answer 10

How is it B?

Answer 11

because you said +1
I'm confused now :/

Answer 12

I was explaining how I got the 1

Answer 14

answer is D

Answer 15

Ahhh Sprauger!!

Answer 16

Sorry answer is A

Answer 17

I know that...

Answer 18

\[C=p(1-d) Divide by p we get, C \div d=1-d C \div d + 1 = -d \And adjusting we get \]
