Step 1: Understand the basic economic principle of supply and demand, which states that if the supply of a good increases while demand remains constant, the price of that good tends to decrease.
Step 2: Identify that Mansa Musa's increase in the gold supply means there was a significant increase in the quantity of gold available in the market.
Step 3: Recognize that with more gold available (higher supply) and assuming demand for gold did not increase proportionally, the market would experience a surplus of gold at the original price.
Step 4: Apply the law of supply and demand, which predicts that this surplus would put downward pressure on gold prices, causing them to decrease.
Step 5: Conclude that the increase in gold supply by Mansa Musa led to a decrease in gold prices, as the supply increase outpaced demand.
