Answer:
d. $681.15
Step-by-step explanation:
Bedroom 1: 
Width = 10 ft
Length = 8.5 ft
Area of bedroom 1 = length × width
= 10 ft × 8.5 ft
= 85 ft²
Bedroom 2:
Width = 11.75 ft
Length = 13.25 ft
Area of bedroom 2 = length × width
= 11.75 ft × 13.25 ft
= 155.6875 ft²
Total carpet in the two bedrooms = 85 ft² + 155.6875 ft²
= 240.6875 ft²
If the
carpet he wants to buy is $2.83 per square foot, then how much will it cost for both rooms?
Total cost for both rooms = Total carpet in the two bedrooms × cost per square foot
 = 240.6875 ft² × $2.83
= $681.145625 
Approximately $681.15
 
        
             
        
        
        
Let the two positive numbers are x , y and there sum is s
So,
            x y = 1024 ⇒⇒⇒⇒ (1)
And        S = x + y ⇒⇒⇒⇒ (2)
by substituting from (1) at (2) with the value of y = 1024/x
∴ s = x + 

Differentiating both sides with respect to x to find the minimum value of the sum and equating to zero
∴  

solve the last equation for x
∴ 
 
    
  ⇒⇒⇒ *x²
∴ x²  = 1024
∴ 

taking the positive number as stated in the problem
x = 32 
So, The numbers are 32 , 32
And theire mimimum sum = 32 + 32 = 64   
 
        
        
        
If y = 0.75 when x = 0.5, set up a proportion - 
0.75:0.5
x:3
Since you have to multiply 0.5 by 6 to get 3, multiply 0.75 by 6 to get your answer: y = 4.5 when x = 3.
