Claire's bedroom floor is 12 1/2 feet by 15 1/4 feet. she wants to buy new carpeting to cover her bedroom floor. if the total cost of the carpeting is $762.50, what is the unit price of the carpet per square foot?

We know that

12 1/2> (12*2+1)/2> 25/2 ft
15 1/4> (15*4+1)/4> 61/4 ft

the bedroom floor area is > (25/2)*(61/4)> 1525/8> 190.625 ft²

If the total cost of the carpeting is $762.50
then
762.5/190.625> $4 /ft²

the answer is 
 the unit price of the carpet per square foot is $4
