Answer:
7 < y
Step-by-step explanation:
The relation you're interested in is ...
(4.5 -2y)/5 < (2 -3y)/10
9 -4y < 2 -3y . . . . . . . . . multiply by 10
7 < y . . . . . . . . . . . . . . . . add 4y-2
The value of the first fraction will be less than that of the second fraction for values of y greater than 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.
