Answer:
Cost of purple carpet for Claire's bedroom is $1033.92.
Step-by-step explanation:
Given:
The dimension of bedroom are given as 16 feet and 18 feet.
Hence we can say that;

Cost of carpet per square feet = $3.59
Hence Cost of carpet for 288 square feet is ;
we will unitary method to find the same;
Cost of carpet for bedroom = 
Hence Cost of carpet for Claire's bedroom is $1033.92.
