Answer:
The digit 4 should be in the thousand position in the number sought;
Examples
9.30<u>4</u>,
9.00<u>4</u>
Step-by-step explanation:
Here, we are required to consider decimal places of numbers
The digit 4 in the number 3.8463 is in the hundredth position
That is 0.04
We are asked to look for the number with a digit 4 that has the same value as
the digit 4 in 3.8463
That is

Therefore, the digit 4 in the number sought should be in the thousandth position, that is 0.004
Example includes 9.304 or 9.004.

THREE LINEAR EQUATIONS WITH THREE VARIABLES
A chemist has three different acid solutions. The first acid solution contains 15% acid, the second contains 25%,
and the third contains 70%. He wants to use all three solutions to obtain a mixture of 40 liters containing 45%
acid, using 2 times as much of the 70% solution as the 25% solution. How many liters of each solution should be used?
How to set up as three linear equations to find the answer?

set up 2 equations
the first equation...
15%*x+25%*y+70%*2y=45%*40
0.15x+0.25y+1.4y=0.45*40
0.15x+1.65y=18
multiply all terms by 100
15x+165y=1800
divide all terms by 15
x+11y=120
the second equation...
x+y+2y=40
x+3y=40
x=40-3y
substitute into the first equation x+11y=120
40-3y+11y=120
40+8y=120
8y=120-40
8y=80
y=80/8
y=10 liters
x+3*10=40
x+30=40
x=40-30
x=10 liters
10 liters of 15%, 10 liters of 25%, and 20 liters of 70%
check:
10*15%=1.5
10*25%=2.5
20*70%=14
1.5+2.5+14=18
18/40=9/20=45/100=45%
45%*40=18

<u>The formula for the monthly payment</u>.....
, where P = the principal amount, r = the monthly interest rate and n = the total number of months.
Here annual interest rate is given as 4.5%
So, the monthly interest rate 
Total number of months 
Also given that, the principal amount is $225000
a. So, the monthly payment will be.....
![M= \frac{P(1+r)^nr}{[(1+r)^n] -1}\\ \\ M= \frac{225000(1+0.00375)^3^6^0*0.00375}{(1+0.00375)^3^6^0 -1}\\ \\ M= \frac{225000(1.00375)^3^6^0*0.00375}{(1.00375)^3^6^0 -1} \\ \\ M \approx 1140](https://tex.z-dn.net/?f=M%3D%20%5Cfrac%7BP%281%2Br%29%5Enr%7D%7B%5B%281%2Br%29%5En%5D%20-1%7D%5C%5C%20%5C%5C%20M%3D%20%5Cfrac%7B225000%281%2B0.00375%29%5E3%5E6%5E0%2A0.00375%7D%7B%281%2B0.00375%29%5E3%5E6%5E0%20-1%7D%5C%5C%20%5C%5C%20M%3D%20%5Cfrac%7B225000%281.00375%29%5E3%5E6%5E0%2A0.00375%7D%7B%281.00375%29%5E3%5E6%5E0%20-1%7D%20%5C%5C%20%5C%5C%20M%20%5Capprox%201140)
Thus, the monthly payment will be approximately $1140
b. The <u>total amount paid</u> over the term of the loan will be:
c. As the principal amount was $225000 , so the amount of interest 
So, the percentage of amount that is paid toward the principal 
and the percentage of amount that is paid toward the interest
