Answer:
Double
Explanation:
If the price level doubles, the good becomes twice as expensive. To be able to afford to the same amount of goods before the doubling in price, the nominal money demanded has to double also.
For example, if $10 could buy 5 pencils. The price of pencils is $2. If the price of pencils increases from $2 to $4 ,$10 would buy 2.5 pencils. For the consumer to be able to buy the same amount of pencils before the price rise, the nominal quantity of money demanded should increase to $20 to be able to buy 5 pencils.
