In ticket maschine were together one hundred coins. They were only 20 and 50 cent coins. The sum total was 29 euros and 60 cents. How many were in ticket maschine coins and which type?

Result

x =  68 (20 cent)
y =  32 (50 cent)

Solution:


x+y = 100
0.2x + 0.5y = 29.6

x+y = 100
0.2x+0.5y = 29.6

x = 68
y = 32
