Coins

In the ticket machine 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 machine coins, and which type?

Correct answer:

x =  68 (20 cent)
y =  32 (50 cent)

Step-by-step explanation:


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

x+y = 100
0.2•x + 0.5•y = 29.6

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

x = 68
y = 32
