Answer:
a. 9,000; 10,000
Step-by-step explanation:
The computation is shown below:
The money multiplier is
= 1 ÷ 0.10
= 10
Now If $1,000 are deposited in banks and the expected reserve ratio is 0.10 ration so the lending amount is $900.
And now if we considered the money multiplier, so it would be increased by
= $900 × $10
= $9,000
And, the increase in money supply is
= $9,000 + $1,000
= $10,000
Hence, the correct option is a.
