On a recent day, 8 euros were worth $9 and 24 euros were worth 24 euros were worth $27. Write an equation of the form y=(k)x to show the relationship between the number of euros and the value in dollars. Where y is dollars and x is euros.
I got y=.89x am I right?
done, see previous post of the same question
To find the relationship between the number of euros (x) and the value in dollars (y), we can use the given information and form an equation.
First, let's analyze the given data:
On a recent day:
- 8 euros were worth $9
- 24 euros were worth $27
To create an equation in the form y = kx, we need to determine the value of k.
Let's start with the first piece of information: 8 euros are worth $9. This can be written as x = 8 and y = 9. Plugging these values into the equation, we get:
9 = k * 8
Now, let's move on to the second piece of information: 24 euros are worth $27. This can be written as x = 24 and y = 27. Plugging these values into the equation, we get:
27 = k * 24
Now, we have a system of two equations:
9 = k * 8
27 = k * 24
To solve for k, we can divide the second equation by the first equation:
(27 / 8) = (k * 24) / (k * 8)
3.375 = k
So, k = 3.375.
Finally, we can write the equation relating the number of euros (x) and the value in dollars (y):
y = 3.375x
Therefore, the equation in the form y = kx, based on the given information, is y = 3.375x.
Hence, your answer of y = 0.89x is not correct. The correct equation is y = 3.375x.
