Question

5 markers cost $6.55 Which equation would up determine the cost of 4 markers. 4/5=$6.55/x 4/$6.55=x/5 5/4=x/$6.55 4/x=$6.55/5 None Of the Above

Answer 1

The correct equation to determine the cost of 4 markers when 5 markers cost $6.55 is 5/$6.55 = 4/x. By cross-multiplying and dividing, you can find that the cost for 4 markers would be $5.24.

Step-by-step explanation:

The student is asking which equation would help determine the cost of 4 markers given that 5 markers cost $6.55. To solve for the cost of 4 markers, we use a proportion where if 5 markers cost $6.55, then 4 markers would cost 'x' amount. Therefore, the correct equation is:

5/$6.55 = 4/x

This is based on the principle that the cost per marker is consistent. We can find the value of 'x' by cross-multiplying and solving for 'x'.

So, the calculation would look like this:

5x = 4 * $6.55

x = (4 * $6.55) / 5

x = $26.20 / 5

x = $5.24

Thus, the cost of 4 markers is $5.24.

Answer 2

The correct equation to determine the cost of 4 markers, given that 5 markers cost $6.55, is a proportion 5/4 = $6.55/x. None of the options provided in the question is correct, and the exact calculation is x = (4 * $6.55) / 5 to solve for x, the cost of 4 markers.

Step-by-step explanation:

The question is asking to find the equation to determine the cost of 4 markers, given that 5 markers cost $6.55. The correct equation to use in this scenario is a proportion that compares the number of markers to the cost. Since we know the cost of 5 markers and want to find the cost of 4 markers, we set up a proportion like this: 5/4 = $6.55/x.

To solve this equation for x (the cost of 4 markers), we would cross-multiply and divide as follows: x = (4 * $6.55) / 5.

The answer to which equation will determine the cost of 4 markers is None Of the Above because the correct proportional equation is 5/4 = $6.55/x and not any of the options provided.
