If 50 feet of electrical wire cost $4.80, then $1o.80 will buy how many feet of the wire
50/4.80 = x/10.80
Solve for x.
To find out how many feet of wire can be purchased with $10.80, we can set up a proportion based on the given information.
Let's start with the given information:
50 feet of wire cost $4.80.
We can set up a proportion using the cost and length of the wire:
50 feet of wire is to $4.80 as x feet of wire is to $10.80.
Using cross-multiplication, we can solve for x:
(50 feet of wire) * ($10.80) = ($4.80) * (x feet of wire)
540 feet of wire = 4.80x
Now, let's solve for x:
x = (540 feet of wire) / 4.80
x ≈ 112.50 feet of wire
Therefore, $10.80 will buy approximately 112.50 feet of electrical wire.
