If the cost of x meters of wire is d dollars, then what is the cost of y meters of wire at the same rate?
$xy/d
$xd
$yd
$yd/x

Answer 1

To determine the cost of y meters of wire, we first need to establish the cost per meter of the wire based on the information given.

The cost of x meters of wire is d dollars. Therefore, the cost per meter is:

\[
\text{Cost per meter} = \frac{d}{x}
\]

Now, if we want to find the cost for y meters of wire, we can multiply the cost per meter by y:

\[
\text{Cost for } y \text{ meters} = y \times \left(\frac{d}{x}\right) = \frac{yd}{x}
\]

Thus, the cost of y meters of wire at the same rate is:

\[
\frac{yd}{x}
\]

So, the correct answer is:

**$yd/x**
