Answer:

Step-by-step explanation:

A room that contains 28 square yards was carpeted at a cost of $322. If
ASHA 777 [7]

The cost for carpeting 20 square yards is $230.

Further explanation:

First of all, we will calculate the cost for one square yard then will find the final answer.

So,

Given

Total area = 28 square yards

Cost of carpeting 28 square yards = $322

Cost of carpeting one square yard = 322/28 = $11.5 per square yard

Now to find the cost of carpeting 20 square yards

Cost of 20 square yards = 20*11.5

= $230

The cost for carpeting 20 square yards is $230.
