Step-by-step explanation:
B = g + 12
g + b = 124
Replace the b in the second equation with
g+ 12
g+ g+12=124
2g + 12 = 124
Subtract 12 from both sides
2g = 112
Divide by 2
g = 56
b= 56 + 12
b= 68
Since he sold it for $75 more,
% Mark Up = Mark Up/ Cost Price x 100%
% Mark Up = 75 / 125 x 100% = 0.6 x 100% = 60%
Percent Mark Up = 60%
Hope this helps :)
