B)P=$1,200
C)P= $900
D)p=$1,100

Answer 1

PLEASE CAN ANY ONE HELP ME

Answer 2

I = Prt
solve for P

P = I/rt

--> 81/.09 = 900

and so on

Answer 3

What do you need help with? Do you understand the formula you are supposed to use?

Answer 4

no i dont

Answer 5

Did you read the problem? The last sentence tells you the formula.

Answer 6

I=prt

Answer 7

yes but i suck in math and i just dont get it and this is the last one i have to do im trying to get dome so i can go to sleep

Answer 8

The fact that you suck in math means you have to work at it harder.
In the formula I is the interest. That's what you are supposed to find.

Answer 9

The way that you find it is by multiplying. What is the principal in the first example in the problem?

Answer 10

The answer is that you don't know what the principal is. That's what you are supposed to find.

Answer 11

What is the interest earned?

Answer 12

900

Answer 13

$81 over 3 years at an interest rate of 3%
That is the first problem and it means that the interest is $81
the time is 3 years and the rate is 3% which is .03
So if you use your formula you have: 81=P(.03)(3)

Answer 14

Solve that for P

Answer 15

SO I HAVE TO DO 81X3%

Answer 16

\[81=P(.03)(3)\]
81=P(.09)

Answer 17

Do you understand that much?

Answer 18

yes

Answer 19

\[\frac{81}{.09}=\frac{P(.09)}{.09}\]

Answer 20

Do you understand that?

Answer 21

i tried to do the second one but i got 4

Answer 22

The second one:
\[80=P(.05)(2)\]

Answer 23

Answer 25

Answer 26
