Answer:
The silver is now 50 years old and the gold coin is 18 years old
Step-by-step explanation:
first the silver was 32 years old , and it said it would be three times as old as the gold coin, to find the gold coin is to divide 32 and 3 together, that would be 10.6 but you can round the number up, you get 10 years.
