It takes 4 years for a principal of $25,000 at a simple interest rate of 5% to become 30,000
<em><u>Solution:</u></em>
Given that:
principal = $ 25000
rate of interest = 5 %
Total amount = $ 30000
Number of years = ?
Formula used:
Total amount = principal + Simple interest
30000 = 25000 + Simple interest
Simple interest = 30000 - 25000
Simple Interest = $ 5000
<em><u>The simple interest is given as:</u></em>

Where, "p" is the principal
"n" is the number of years
"r" is the rate of interest
Substituting the values in formula, we get

Thus it takes 4 years for a principal of $25,000 at a simple interest rate of 5% to become 30,000
Answer:
The answer is <em>x<-9</em>
Step-by-step explanation:
x+5<-4
You move it to the right and you change the sign
This is what I mean: x<-4-5
Then you Calculate the Difference
So it will be: <em>x<-9</em> which is your answer
Answer:
<em>30(30 - x) = 540 </em>
Step-by-step explanation:
A = l w
<u><em>30(30 - x) = 540</em></u>
Hello,
the first step should be to distribue:
-4(3-5x)= -12+20x
Teh resolution may be:
-4(3-5x)>=-6x+9
==>-12+20x>=-6x+9
==>20x+6x>=9+12
==>26x>21
==>x>=21/26
But an other way may be used:
-4(3-5x)>=-6x+9
==>3-5x<= -6x/(-4)+9/(-4)
==>-5x-3/2 x<=-9/4 -3
==>-13/2 x <=-21/4
==>x>= -21/4 *(-2/13)
==>x>=21/(2*13)
==>x>=21/26
BANK A:
5,000*0.03*5=750
BANK B:
5,000*0.025*6=750
They are the same
