Determine 3805

Denis has 43% more money than Damian, and Zuzana has 12% less money than Damian. They have a total of 165 euros and 50 cents. Determine how much money Denis, Damian, and Zuzana have.

Correct answer:

a =  71.5
b =  50
c =  44

Step-by-step explanation:


a=1.43 b
c = (1-0.12)b
a+b+c=165.50

a=1.43•b
c = (1-0.12)•b
a+b+c=165.50

a-1.43b = 0
0.88b-c = 0
a+b+c = 165.5

a = 143/2 = 71.5
b = 50
c = 44
