How much will he pay for what? There isn't an end amount stated so it is an impossible question.
If you want to find 1 gallon, divide 27.44 by 7 (= 3.92)
Then multiply 3.92 by whatever amount you require.
I can't give you the exact answer because I think you may have missed out some of the question! Sorry x
X = 20
If you multiply both sides by 5 to get rid of the fraction ( x - 60 = -40 ) the answer would become clear.
The answer is d 34x(8,000+10)
Answer:

Step-by-step explanation:
Given
Round 0 1 2 3
Points 25 75 225 675
Required
Determine the equation
Let n = rounds and p = points.
So, we have:



The above shows a geometric progression.
So, we solve using

In 
n = 0 and p = 25
Substitute these values in 




In 
n = 1 and p = 75
Substitute these values in 


Substitute 25 for a

Make b the subject


So, we have:
and 
The equation
becomes
