Answer: $10 billion
Explanation:
Increase in the money supply can be calculated by multiplying the injection of cash into the economy by the Money Multiplier which is calculated as;
= 1/ reserve ratio
Reserve ratio = 10%
Money Multiplier = 1 / 10%
= 10
The money supply will therefore increase by;
= 1,000,000,000 * 10
= $10,000,000,000
= $10 billion
