X = 39ft
It’s the same units as house A it’s just a reflection
        
             
        
        
        
A product increases its value because of the imposition of  tax. For example, a medicine that cost $1 can be bought possibly at $1.4 because of the value added tax. To determine the original bill without tax, the equation is $7.95/1.06. This is equal to $7.5.
        
             
        
        
        
This is what I get.  Total will be 4187.56 with  Interest 2187.56.  
By using the formula:
To find amount :
A=p (1+r/n)^n×t
Where
P=2000,r=3%,n=1,t=25
So plug in and solve  A=2000(1+0.03/1)^1×25  
To find interest you use formula  A=p+I
A=4187.56, p=2000,i= we need to find.
4187.56=2000+I
4187.56-2000=I
2187.56=i
 
        
             
        
        
        
A=1/10, b=1/12, c=1/15  (these are the rates for each worker...)
1.)
2(1/10)+4(1/12)+t/15=1
1/5+1/3+t/15=1
(3+5+t)/15=1
3+5+t=15
8+t=15
t=7
So it would take c 7 hours to finish the job.
2.)
1/40-1/60
(3-2)/120
1/120
The drain rate is 1/60.  So you will need to find t when the tank is empty, while starting at 2/3 capacity...
2/3-t/60=0
(40-t)/60=0
40-t=0
t=40
It would take 40 minutes to empty the tank when it is 2/3 full.
        
             
        
        
        
the amount of money rick earned can be solve using the
formula:
F = P (1+ i)^n
Where F is the future money
P is the initial money
i is the interest rate
n is the time
F = 1000 ( 1 + 0.04)^10
F = $ 1,480.24
Sally
F = 1000 + (50)(10)
F = $ 1500
So the answer is D
