Question

Select the correct answer.

Answer 1

The correct answer is A

Answer 2

Answer: B. 239 Square Feet

Step-by-step explanation:

Let y be the size of a kitchen that costs $3,824.00.

Given : The price of tiling a room varies directly as the size of the room.

Equation of direct variation between x and y : $\dfrac{x_1}{x_2}=\dfrac{y_1}{y_2}$

If the tiling costs 4,224.00 for 264 square feet , to find the  size of a kitchen that costs $3,824.00.

We put $x_1= 4224 \ \ ; \ y_1=264\ ; \x_2=3824\ ; \ y_2=y$ , we get

$\dfrac{4224}{3824}=\dfrac{264}{y}\\\\\Rightarrow\ y=\dfrac{264\times3824}{4224}=239$

Hence, the size of a kitchen that costs $3,824.00 is 239 Square Feet

The correct answer is B. 239 Square Feet
