I asssume we want to find the original price
so marked up 50% means if original price=100, then marked up price=50+100=150%
so
36.76=150%
hack, since 150=3 times 50 and 2 times 50=100, divide 36.76 by 3 then mutiply by 2
36.76=150%
divide both sides by 3
12.25333333333=50%
multiply both sides by 2
24.5=100%
original price=$24.50
6x²-5x-4=0
x=(-b+/√b²-4ac)/2a
D=b²-4ac=25+4*6*4=121, √D=√121=11
x=(5+/-11)/12
x1=-6/12=-1/2
x2=16/12=4/3

Answer:
(-a-b,c)
Step-by-step explanation:
midpoint D : ((-2b-2a)/2 ;(2c+0) /2 )
(-2b-2a)/2 = 2(-b -a)/2 = -b-a
(2c+0) /2 =2c/2 = c
