Final answer:
In 2021, $900 can buy 112 crab cakes. In 2022, with a 30% increase in the money supply, $900 can buy 86 crab cakes. The impact of printing money on the value of money is known as inflation.
Step-by-step explanation:
In 2021, with a crab cake priced at $8, we need to calculate the quantity of crab cakes that can be bought with $900. To do this, we divide $900 by $8:
Quantity = $900 / $8 = 112.5
Since we cannot buy a fraction of a crab cake, we round down to the nearest whole crab cake:
Quantity = 112
In 2022, the money supply is increased by 30%. This would result in an increase in the price of the crab cake. To find the new price, we multiply the original price by 1.3:
New Price = $8 * 1.3 = $10.40
To calculate the quantity of crab cakes that can be bought with $900, we divide $900 by the new price:
Quantity = $900 / $10.40 = 86.54
Again, we round down to the nearest whole crab cake:
Quantity = 86
The impact of the government's decision to raise revenue by printing money on the value of money is known as inflation.
