Question

I deathly need help!

Answer 1

Answer:

So we rearrange the equation to R=I/PT

Then we substitute: R= 90/300(2)

Calculating the answer should be about 0.15

or I =15%

Step-by-step explanation:

Answer 2

First we find how to get $90 from 300 with a percentage rate of X.

To find the interest rate the formula give is
I = P x R x T.

Now substitute the variables.

90 = 300 x R x 2

90 = 600 x R

To find R we divide.

90/600 = .15

Now we substitute,

300 x .15 x 2 = 90

R = .15 or 15%

Hope this helps!
