Begin by computing the <span>monthly interest rate like this:
</span>

<span>Each month, we have to substract from $463 the monthly rate and the payment of 5%, which result in the following formula:
</span>

<span>
So, after three months, it ill remains $381.5 in </span><span>Bridgette account. </span>
 
        
        
        
Answer:
a=21
AB=23.9
BC=19.5
CD=(23.9)
AD=19.5
Step-by-step explanation:
Each pair of parallel sides are equal in a parallelogram. Sense both pairs use the same variable we can just choose the easiest to solve which would be:
a-1.5=19.5
add 1.5 to both sides
a=21
now substitute 21 in for a in each equation.
AB=CD so
AB=23.9
BC=AD so 
BC=19.5
CD=(21)+2.9 so
CD=(23.9)
AD is given so
AD=19.5
 
        
             
        
        
        
That is true because the square root of 32 is about 5.66, so 4.65 IS less than it.
