Answer:
This would mean that the next year her car's value would go down by $2,625. The new value of the car would consequently be $34,875.
<h3><u>
Step-by-step explanation:</u></h3>
<em>Here is how you can solve this problem:</em>
- Okay, so first, let's find 7% of $37,500. To do this, the simple way would be to find first 1% of $37,500.
- 1% of $37,500 is $375. This is because you are moving the decimal point two spaces to the left.
Now that we know that 1% of $37,500 is $375, let's multiply this value by 7.
- Subtract 2625 from 37,500.
Let's say that the next year, her car value goes down by 7% again.
THIS IS THE IMPORTANT PART:
<em>YOU FIND 7% OF THE NEW VALUE, NOT $37,500. YOU WOULD FIND 7% OF $34,875.</em>
<em>Hope this helps! :) </em>
<h3>The interest rate is 8 % if your balance on an investment of 857 dollars at the end of six years is 1268.36 dollars</h3>
<em><u>Solution:</u></em>
Given that,
Principal = $ 857
Amount = $ 1268.36
Number of years = 6
Rate of interest = ?
Simple Interest = Amount - principal
Simple Interest = 1268.36 - 857
Simple Interest = 411.36
<em><u>Use the formula,</u></em>
Thus the interest rate is 8 %
