Question

EMERGENCY 11??? DUE TOMORROW

Answer 1

First, we plug in the numbers.

$40 = P(4%)(2)

4% = 0.04

40 = P * 0.04 * 2

Divide each side by 2

20 = P * 0.04

Divide by 0.04

P = 500

Lets check it!

500 * 0.04 * 2 = 40

500 * 0.04 = 20

20 * 2 = 40

40 = 40

Answer 2

Answer:

a. I/rt= P

b. $500

Step-by-step explanation:

A.  I=Prt

divide both sides by rt

I/rt= P

B.

I/rt= P

40/(.04*2) =P

40/.08 = P

500=P
