<h3><u>Question:</u></h3>
On a recent day, 8 euros were worth $9 and 24 euros were worth $27. Write an equation of the form y = kx to show the relationship between the number of euros and the value in dollars.
<h3><u>Answer:</u></h3>y = 1.125x is the equation to show the relationship between the number of euros and the value in dollars.
<h3><u>Solution:</u></h3>Given that On a recent day 8 euros were worth 9 dollars and 24 euros were worth 24 dollars
Let "y" be the value in dollars
Let "x" be the number of euros
We have to write a equation in form of y = kx
<em><u>8 euros were worth 9 dollars</u></em>
"k" is found as follows:
Therefore, equation of y = kx is given as:
To check the equation, use the another given value
24 euros were worth $27
Hence the equation y = 1.125x is correct
Answer:
Total interest =$1296
Step-by-step explanation:
Kevin invested $8,000 for one year at a simple annual interest rate of 6 percent
Simple interest =
P=8000, n=1 year and r=6
interest =
Interest = 480 dollars
P= 10000, t=1, r=8%=0.08, n=2 for semiannually
Interest = 10816- 10000=816
Total interest =
