Answer:
61
Step-by-step explanation:
So basically you separate the numbers like 1 1 1 1 0 1, and time 2 while having the number of numbers as the exponent decreasing. Like this, 1x2^5+1x2^4+1x2^3+1x2^2+0x2^1+1x2^0. Then figure it out and it would be 32+16+8+4+0+1=61. If don't understand, look at the picture below 
 
        
             
        
        
        
The material costs 5.37 for 1 yard.
 Multiply the cost of 1 yard by the number of yards bought:
5.37 per yard x 4.75 yards = $25.51 Total cost.
The answer would be D.
