Answer/Solution
80
Steps/Work
C
K1 = 5x
A1 = 3x
K2 = 5x - 10
A2 = 3x + 10
K2/A2 = 3/2
(5x-10)/(3x+10) = 3/2
2*(5x-10) = 3*(3x+10)
10x - 20 = 9x + 30
x = 50
K2 = 5*50 - 10 = 240
A2 = 3*50 + 10 = 160
K2 - A2 = 80
Answer : E
K1 = 5x
A1 = 3x
K2 = 5x - 10
A2 = 3x + 10
K2/A2 = 3/2
(5x-10)/(3x+10) = 3/2
2*(5x-10) = 3*(3x+10)
10x - 20 = 9x + 30
x = 50
K2 = 5*50 - 10 = 240
A2 = 3*50 + 10 = 160
K2 - A2 = 80
Answer : E
