If the federal reserve decreases the reserve rate from 7% to 5%, how does this affect the amount of money that would result because of fractional-reserve banking from an initial deposit into a bank of $30,000?

The total affect of the decrease in the interest rate = $29400

Step-by-step explanation:

The initial amount of money which has been deposited into the account = $30000

The rate at which the initial money was deposited = 7%

But it is given that the federal reserve decreases the reserve rate from 7% to 5%

Now, we need to find the affect of this decrease on the deposited money

The rate of change in the interest rate = 7 - 5 = 2%

So, The affect of this decrease = 2% of 30000

                                                    = $600

So, The money becomes = 30000 - 600

Therefore, The total affect of the decrease in the interest rate = $29400

c.

step-by-step explanation:

she should of added 9^2 and 12^2. that is because it is a^2+b^2=c^2. c^2 is the hypotenuse and should always be bigger than the other two numbers. which is why she should of added 9 squared and 12 squared together instead of 15 squared.
