 is the answer
Step-by-step explanation:
Equation of the line: y = 6/5x + 1
                         = 5y = 6x + 5
                         = 6x - 5y + 5
Equation of the perpendicular line: bx - ay + k = 0
                                                        = -5x -6y + k = 0
Equation passes through (6,-6),
-5(6) -6(-6) + k = 0
-30 + 36 + k = 0
6 + k = 0
k = -6
Substituting,
-5x -6y + k = 0
-5x -6y -6 = 0
-6y = 5x + 6

First you have to have the absolute value isolated so the 2 has to be divided. Then set up the two cases and solve.
 
        
        
        
Convert percentages to units.
100% - 20% = 80% = 0.8
100% - 25% = 75% = 0.75
Then multiply those together:
0.8*0.75=0.6=60%
100% - 60% = 40%. That's the overall price percentage reduction.
P.S. You can convert percentages to units by diving % by 100 for example 100% divided by 100 is equal to 1.
And vice versa aka multiply units by 100 and you get %, for example 0.8 times 100 is 80%
