 Option D is the correct answer.
Step-by-step explanation:
Step 1 :
Let A represent the cost of one bucket of apple and P represent the cost of one bucket of peaches.
So we have , 
4 buckets of apples and 5 buckets of peaches for $64
8  buckets of apples and 3 buckets of peaches for $72
Writing this in the equation form we have,
4A + 5P = 64
8A + 3P = 72
Step 2:
Solving for the above 2 equations we can get the required costs 
Equation 1 is 
4A + 5P = 64 , Multiplying this by 2 we have 8A + 10P = 128 
Equation 2  = 8A + 3P = 72
Subtracting both we have , 7p = 56 = > P = 8
Substituting this in equation 1 we have 
8A + 80 = 128 => A = 6
Hence the cost of one bucket of apple is $6 and the cost of one bucket of apple is $8.
Option D is the correct answer.

Answer:
135 
Step-by-step explanation:
30÷2≡15 
<h3>15×9≡135</h3>
 
        
             
        
        
        
The expression which relates the total time taken and the time taken for the trip is [15s + 15(s+2)] / s² + 2s and 2.32 hours respectively. 
<em>Travel time = distance ÷ speed </em>
<u>Second half of the trip</u> : 
- <em>Distance covered = 15 miles</em> 
<u>Time taken for second half of trip</u> :
Time taken = 15 / s 
<u>First half of the trip</u> :
- <em>Speed = s + 2 mph </em>
<u>Time taken for first half of trip :</u>
Time taken = 15 / (s+2)
<u>Total time taken :</u> 
<em>First half + second half</em> 
15/(s+2) + 15/s = [15s + 15(s+2)] / s² + 2s
B) 
If s = 12 
<em>Substitute s = 12 into the expression</em> : 
[15(12) + 15(12+2)] / 12² + 2(12)
[180 + 210] / 144 + 24 
390 / 168
= 2.32 hours 
Therefore, the total time taken is 2.32 hours.
