Answer:
-3x^2-22x-7
Step-by-step explanation:
 
        
             
        
        
        
<h3>Given:</h3>
- P= $12500
- R= 10%
- T= 3 years
<h3>Note that:</h3>
- P= Principal amount 
- R= Rate of interest 
- T= Time period 
<h3>To find:</h3>
- The simple interest
- The total amount paid
<h3>Solution:</h3>

First, we'll have to multiply, principal amount (12500), rate (10) and time period (3).


Now, we'll have to divide the amount (375000) by 100.

<em>I=$3750</em>
Now, we can find the total amount paid.

Let's substitute according to the formula.

<em>A=$16250</em>
<u>Therefore</u><u>,</u><u> </u><u>simple</u><u> </u><u>interest</u><u> </u><u>is</u><u> </u><u>$</u><u>3</u><u>7</u><u>5</u><u>0</u><u> </u><u>and</u><u> </u><u>$</u><u>1</u><u>6</u><u>2</u><u>5</u><u>0</u><u> </u><u>was</u><u> </u><u>paid</u><u> </u><u>in</u><u> </u><u>total</u><u>.</u>
 
        
        
        
1.  y = c - x
2.  y = ( t - 3x ) / 2
3.  y = ( 4p ) / 3
4.  y = ( 2 - 4s ) / 3s
