Answer:
<h3>The answer is option A</h3>Step-by-step explanation:
Let the price of the room be p
Let the size of the room be s
To find the size of a kitchen that costs $3,824.00 we must first find the relationship between them
The statement
The price of tiling a room varies directly as the size of the room is written as
<h3>p = ks</h3>where k is the constant of proportionality
when
p = $4,224.00
s = 264 square feet
Substitute the values into the expression to find k
That's
4224 = 264k
Divide both sides by 264
k = 16
So the formula for the variation is
<h3>p = 16s</h3>when
p = 3824
s = 239
The final answer is
239 square feet
Hope this helps you
