Answer:
The number of gallons of 100% mixture to be added is 6.11 gallons and the 10% mixture to be added is 48.89 gallons.
Step-by-step explanation:
Let us assume that x gallons of 10% mixture and y gallons of 100% mixture are added to make 55 gallons of 20% mixture.
So, x + y = 55 ............. (1)
And
⇒ 0.1x + y = 0.2x + 0.2y
⇒ 0.1x = 0.8y
⇒ x = 8y ........... (2)
So, from equation (1) we get, 8y + y = 55
⇒ 9y = 55
⇒ y = 6.11 gallons.
Therefore, the number of gallons of 100% mixture to be added is 6.11 gallons and a 10% mixture to be added is (55 - 6.11) = 48.89 gallons. (Answer)

Given
Craftsman sell 10 Jewelry set for $500 each
For each additional set he will decrease the price by $ 25
Suppose he sells n set over 10 set
Earning

The equation of that line from from picture is -x+4
2/2=1 with y intercept on 4
Since if is perpendicular we can assume that the equation should be positive. Eliminate the negative answers.
Negative reciprocal= x+1/4
