The difference between what Richard and Albert spent and what Conrad and Albert spent = The difference betwee what Richard spent and what Conrad spent = Four times of what Conrad spent = $1067 - $555 = 4 x $128 Since Conrad spent $128, Albert spent $555 - $128 = $427 (ans)

B+D = A+C 31+19=50 50-22= 28

Alternatively, see that B+D is half area of rectangle. Thus area of whole rectangle is 2*(19+31)=100. Therefore A=100-19-22-31=28. :-)
