Answer: $70,000 of new money and the money supply in the economy will be equal to $70,000
Step-by-step explanation:
The reserve ratio is the percentage of deposit the banks are expected to keep for demand by customer and the remaining percentage is made available for loan to customer.
In the above scenario the reserve ratio is 10% which gives a multiplier of 1/0.1 which gives 10. The money supply is the deposit multiply by the the multiplier $7000*10 which gives $70,000 as money supply.
