$8370 of the deposit money $9000 is the money the bank is free to lend given that the reserve rate is 7%. This is obtained by finding 7% of deposit money and subtracting the answer from the deposit money.
Given that, deposit = $9000
reserve rate = 7%
First we have to find 7% of $9000,
7% of $9000 = 7/100 × $9000
= $630
Money the bank is free to lend, $9000 - $630 = $8370
Hence $8370 of the deposit money $9000 is the money the bank is free to lend given that the reserve rate is 7%.

Answer:
f^-1(x)=1/2x+5
Step-by-step explanation:
y=2x-10
inteechange 'y' with 'x'
x=2y-10
make 'y' the subject
2y=x+10
divide by 2both sides
y=(x+10)÷2
y=1/2x+5
f^-1(x)=1/2x+5
Answer: the account earns interest of $40.16
Step-by-step explanation:
We would apply the formula for determining compound interest which is expressed as
A = P(1+r/n)^nt
Where
A = total amount in the account at the end of t years
r represents the interest rate.
n represents the periodic interval at which it was compounded.
P represents the principal or initial amount deposited
From the information given,
P = 875.83
r = 9% = 9/100 = 0.09
n = 12 because it was compounded 12 times in a year.
t = 6 months = 6/12 = 0.5 year
Therefore,.
A = 875.83(1+0.09/12)^0.5 × 12
A = 875.83(1+0.0075)^6
A = 875.83(1.0075)^6
A = 915.99
The interest that she earns is
915.99 - 875.83 = $40.16
Answer:
Step-by-step explanation:
If all were dimes, the total would be $1.30. It is $0.75 more than that.
Each quarter that replaces a dime adds $0.15 to the total, so there must be ...
$0.75/$0.15 = 5
quarters.
Kevin has 8 dimes and 5 quarters in change.
